SMTP Status Codes and Error Messages from Error 571

SQLServerF1

SMTP status code – 571 – I have been told not
to work with you !!!
(Also called SMTP Error 5.7.1)
SMTP Error 571 is usually a subset of SMTP Error 550.
So typically you will get an “SMTP Error 550 571” or an
“SMTP Error 550 5.7.1”. SMTP Error 571 is almost
always the recipient’s server telling your sending
server that “it has been told not to work with you !”.
The explanation text which follows the error response
usually does a good job of telling you why the remote
server does not want to work with your server (typically it
will be because your server/email-address is not
whitelisted, or you are not allowed to send messages
through this ISP’s SMTP server without providing
authentication, relaying not permitted, or your server is on
an RBL blacklist).
Typical SMTP 571 responses are : “5.5.0 SMTP; 571
Delivery not authorized, message refused” or “550 5.7.1
Mail from Ip_Address refused by blackhole site
dialups.mail-abuse.org” or “571 email address we do
not relay” or “550 5.7.1 Relaying prohibited”

SMTP Error The following addresses had
permanent delivery errors
“The following addresses had permanent delivery
errors” / “The following address had permanent
delivery errors” : Either of these sentences are usually
followed by one or more email address(es).
The error message is effectively saying that the email
addresses listed do not exist, or no longer exist (if you
used to be able to email to them successfully). You need
to get the sender to verbally verify with the recipient what
his/her new email address is.

SMTP Error Mailbox is inactive
(The hosting ISP is having problems)
A typical error message might go like this : “A message
that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following
address(es) failed : XXXXXX Mailbox is inactive”.
This error is almost always a problem at the hosting
ISP which hosts the POP box(es) of the recipient’s
email address or domain. You need to inform the
recipient that there is a problem with their hosting
company. So, for example, if you are sending an email to
John.Doe@clara.net and you get the “Mailbox is inactive”
error, then you need to tell John Doe that his hosting ISP,
ClaraNET, are having problems with incoming emails and
that he should talk to them.

Above are list of SMTP Errors Codes and Status Codes along with Error and Warning messages from Error 571 received while performing certain operation against mail server applications or related products.

What are SMTP Error Messages?
Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission. SMTP protocol is used for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP.

In general, each SMTP error contains the following information:
• The SMTP Status Code or SMTP Error Codes or SMTP Reply Codes
• The message text. This text is usually returned with the Error code. Some messages employ word substitution, where the word substituted represents the system-replacement of a term more specific to the occurrence.
• An explanation of how the error may have occurred.

SMTP Status Codes and Error Messages from Error 554

SQLServerF1

SMTP status code – 554 – Transaction failed. Nowadays SMTP status 554 is in most cases returned when the recipient server believes your email is spam or your IP address or ISP server
has been blacklisted on one or more Internet blacklists. or With Yahoo, on the other hand, this usually means the email address does not exist or has been disabled.
or With IBM’s Lotus Domino this is either a Domino bug or a Disk Full error
(also called SMTP Error 5.5.4)
SMTP Error 554 : There was a permanent error trying to
complete the mail transaction which will not be resolved by
resending the message in its current form. Some change
to the message and/or destination must be made for
successful delivery.

For instance, Yahoo often returns the following if the
recipient email address does not exist on the Yahoo
systems : “554 delivery error: This user doesn’t have a
Yahoo.com account”. Another typical Yahoo SMTP Error
554 reply is : “554 delivery error: Sorry your message to
<Email-Address> cannot be delivered. This account has
been disabled or discontinued”.

In the case of an IBM Lotus Domino server on the other
hand, this is either a disk full error (the first thing to
check), or a Lotus Domino bug which has appeared in
various guises in many versions of Lotus Domino as far
back as 2002. Eight years, Eight years and counting and
IBM still suffer from this bug – the mind boggles ! Click
on this link to read the latest IBM Knowledgebase article
on this error at the time of writing :
In most other cases, however, a recipient mail server will
return an SMTP REPLY 554 when its anti-spam firewall
does not like the sender’s email address, or the
sender’s IP address, or the sender’s ISP server
(because, for example, they are listed in an RBL) and
where you will therefore either need to have the sender
whitelist you in their anti-spam program/appliance, or,
worse, you will need to take steps to have either your IP
address or your ISP’s servers (if you send mail through
your ISP) de-listed from one or more RBLs (RBL =
Realtime Blackhole List – also called Realtime Blacklist
nowadays).

For example, a 554 error returned by a Comcast server
might look like this : “Username@comcast.net SMTP error
from remote mail server after initial connection : host
mx2.comcast.net :
554 IMTA11.emeryville.ca.mail.comcast.net <Your-serverIP-address>
was found on one or more DNSBLs, see
http://help.comcast.net/content/faq/BL000010”, where
DNSBLs = DNS Blacklists. In this case, therefore, if you
get such a message back it is telling you your IP address,
or your ISP’s mail server is listed on one of the anti-spam
blacklist databases that Comcast uses to filter out spam on
incoming emails to Comcast mailboxes – click the link
provided in the error message to see how you may be able
to un-blacklist yourself as far as Comcast is concerned. Here is another example from the OZEMAIL ISP in
Australia, “SMTP error from remote mail server after initial
connection to host mx1.ozemail.com.au :
554 filter.ozemail.com.au” – not very informative, as you
can see, but the name of the server returning the SMTP
reply 554 is what gives this away as OZEMAIL’s anti-spam
not liking you : filter.ozemail.com.au. “Filter” in the
name of a recipient server is almost always an indication
that that server is an anti-spam and antivirus server.
And here is a Twitter example : “SMTP error: Email
Error: RCPT TO invalid mail server response:
554 5.7.1 : Recipient address rejected”.
Note that SMTP Error 554 can also often be buried in the
middle of SMTP Error 550 errors. Here is an example of a
recipient mail server returning an SMTP Error 554 because
its Barracuda anti-spam firewall appliance rejected the

SMTP Status Codes and Error Messages from Error 553

SQLServerF1

SMTP status code – 553 – Requested action not taken – Mailbox name invalid. or You are attempting to send emails through a specific ISP’s SMTP server without authentication and without being connected to the Internet through that ISP’s service or You are sending from an Exchange server configured to send via DNS and you do not have a public reverse DNS record pointing back to your Exchange server
(also called SMTP Error 5.5.3)
SMTP Error 553 : There is an invalid email address in
the “To“, “CC”, or “BCC” field of the email message.
Here is a typical SMTP Error 553 response :
”Hi. This is the QMAIL-send program at <ip-address>. I’m
afraid I wasn’t able to deliver your message to the following
addresses. This is a permanent error; I’ve given up. Sorry
it didn’t work out. <Email-address-you’re-sending-to> :
<remote-mail-server-ip> does not like recipient. Remote
host said: 553 5.3.0 <Email-address-you’re-sending-to>.
Addressee unknown. Giving up.”.

SMTP Status 553 is also sometimes returned by an ISP
mail server. When this happens this is almost always
because you are trying to send through a specific
ISP’s SMTP server and yet you are not connected to
the Internet through that ISP; for example : you have
connected to the Internet through a Comcast broadband
connection but your email program (Outlook Express,
Windows Mail, …) is configured to send emails through the
SMTP server of Tiscali. A typical such error message
might be : “553 sorry, relaying denied from your location”.

SMTP Error 553 can also be received if you are sending
from a Microsoft Exchange server configured to send
directly via DNS (rather than by relaying to an ISP’s
SMTP server) and there is no public reverse DNS
record pointing back to the public IP of your Exchange
Server, in which case some receiving mail servers return
a 553 error because they weren’t able to verify that your
server’s HELO name matched its public outgoing IP
address. A typical error message for this 553 response
might be : “5.5.0 smtp;553 sorry, that domain isn’t allowed
to be relayed thru this MTA (#5.7.1)” or “5.5.0 smtp;553
sorry, that domain isn’t in my list of allowed rcpthosts
(#5.7.1)”.

SMTP Status Codes and Error Messages from Error 551 – 552

SQLServerF1

SMTP status code – 551 – User not local or invalid address – Relay denied.
(also called SMTP Error 5.5.1)
SMTP Error 551 : If neither the sending mail address nor
the recipient’s address are locally hosted by the server,
then the ISP’s servers may refuse to relay the message
on.
Some ISPs implement this restriction to thwart spammers.
In our view, here at AnswersThatWork, this is a lazy and
incompetent method of fighting spam as most of the time it
does nothing but inconvenience no-one other than the
ISP’s vast majority of considerate and law abiding users.
In our experience this usually goes hand in hand with

barely competent technical support. At the time of writing,
14-Sep-2008, a typical culprit for this is BT, British
Telecom, in the UK. The way in which it manifests itself is
as follows : you have a domain that is hosted by
CrystalTech.com but your ISP is DodgyISP.com and
you try to send emails from your domain to
WhatANiceBunchOfPeopleYouAre@yahoo.usa.
Neither your domain nor Yahoo.usa are hosted by
DodgyISP.com, as a result your email is not accepted by
DodgyISP’s mail servers and your mail server is returned
an SMTP Error 551. To correct the problem you have to
call DodgyISP.com and ask them to enter your domain
name as an allowed sender.

SMTP status code – 552 – Requested mail actions aborted – Exceeded storage allocation. or Size of the incoming message exceeds the incoming size limit
(also called SMTP Error 5.5.2)
SMTP Error 552 : The recipient’s mailbox has reached
its maximum allowed size (this is often accompanied by
a return mail from your ISP or mail server informing the
sender of the email of just that situation).
Example : “552 sorry, mailbox Alan@ThisCompany.com
is over quota temporarily (#5.1.1)”.
————–
Some mail servers have extended the scope of SMTP
Reply Code 552 by also including errors where the size of
the incoming message exceeds the size limit specified
by the Network Administrator, as in, for example,
“SMTP Error 552 5.2.3 Message size exceeds fixed
maximum message size (7000000)”, which effectively
says that the incoming message was larger than the 7MB
limit (7,000,000 bytes) set by the Network Administrator of
the recipient’s mail server

SMTP Status Codes and Error Messages from Error 541 – 550

SQLServerF1

SMTP status code – 541 – Recipient Address Rejected – Access denied (typically by the recipient’s antispam program / appliance)
(also called SMTP Error 5.4.1)
SMTP Error 541 : This response is almost always sent
back by an anti-spam, intrusion prevention, or mail filtering
appliance / firewall at the recipient’s end.
Typically SMTP response 541 will be tagged along as a
sub-error of SMTP Error 550. For example : “SMTP
error from remote mail server – 550 5.4.1
billing@thatcompany.com : Recipient address rejected
– Access Denied” or one from the Proventia anti-spam
appliance “#5.5.0 smtp;541 Internet Security Systems’
Proventia(TM) intrusion prevention appliance blocked
forwarding of message”.
The only way to solve SMTP Error 541 is to ask the
recipient to whitelist you.

SMTP status code – 550 – Requested actions not taken as the mailbox is unavailable.Usually it is at the recipient’s end, but it could also originate from inside your own “walls” through being caused, for example, by an appliance which scans your outgoing emails once they’ve left your server.
(also called SMTP Error 5.5.0)
550 is always a
problem external to
your own mail server.
SMTP Error 550 : This response can be caused by quite
a few situations.
550 is always a problem external to your own mail
server. Usually it is at the recipient’s end, but it could
also originate from inside your own “walls” through being
caused, for example, by a firewall appliance which scans
your outgoing emails once they’ve left your server.
SMTP Error 550 will be returned by many servers If the
recipient email address simply does not exist on the
remote side (you will often get “550 Invalid recipient” or
“550 User account is unavailable” or “<ip-address-ofremote-server>
does not like recipient – 550 Address

rejected” or “550 No such user here” or “550 Not our
Customer” or “550 Account not available” or “Remote
host said : 550 – Barack.Obama@ThisCompany.com, this
THISCOMPANY.COM Mailbox Does Not Exist – Giving
up”). In this case the sender of the email needs to contact
the recipient verbally to get the correct email address.
————–
SMTP Error 550 will sometimes also be returned by the
recipient’s anti-spam firewall if, for example, the
anti-spam firewall does not like the sender (typically
because the sender needs to be whitelisted). A typical
example of an SMTP Error 550 return message by an
anti-spam firewall might be :
240.240.240.240 does not like recipient.
Remote host said: 550-Verification failed for
John.Doe@YourDomain.com
550-Previous (cached) callout verification failure
550 Sender verify failed
Giving up on 240.240.240.240.
SMTP Error 550 can also be returned by your own mail
and web filtering appliance where the message leaves
your mail server and is intercepted by your web and mail
filtering appliance, before it leaves your premises, and for
whatever configuration reasons it thinks your email is spam
or dangerous for the recipient (in other words it tries to
protect your company from accidentally sending viruses
and accidental spam emails – through a PC being infected
with a bot – to your customers). Here is a typical example
of such a response :
The attached file had the following undeliverable
recipient(s):
John.Doe@comcast.net
Transcript of session follows:
Command: Data…
Response: 550 Cyberoam Anti Spam Engine has identified
this email as a spam. Refid:str=0001.0A0B0206.4BA7422C.01F5,ss=1,vtr=str,vl=0,p

SMTP Status Codes and Error Messages from Error 530

SQLServerF1

SMTP status code – 530 – Authentication is required or Your server has been blacklisted by the recipient’s server or The recipient’s mailbox does not exist
(also called SMTP Error 5.3.0)
SMTP Error 530 : Originally this error has always
pointed to a problem with the SMTP server you are
using requiring authentication (a username +
password every time you send an email), as per the
examples below. However read this entry fully ….
One example would be because that SMTP server,
typically your ISP’s SMTP server, requires all email sent
through it to be done with authentication (and your email
program or server is not configured to do so).

The other classic example of this error is when you are
trying to send emails through a particular ISP’s SMTP
server but you are not doing so through that ISP’s
broadband connection. For example : at home you use
Verizon and you have configured Windows Mail (Outlook /
Outlook Express) on your laptop to send emails through
the Verizon SMTP server available free of charge to you as
a Verizon customer. All works well without authentication.
You then take a vacation to visit friends in Canada and at
their house their wireless Internet is through Telus. The
first time you try to send emails you get a
“530 Authentication is required” error. This is because the
Verizon SMTP server realises that you are trying to access
it through a DSL service not provided by Verizon (your
friends’ DSL service is provided by Telus) and it will only
allow you to access it if you can provide your Verizon
username + password (authentication) thus confirming that

as a paid Verizon customer you are allowed to use their
SMTP server even though you are connecting to it through
a Telus DSL service. If at that point you then configure
Windows Mail / Outlook / Outlook Express to use
authentication, the problem will disappear.
In another example GMAIL (Googlemail) introduces a
secondary SMTP error 570 with its 530 replies. Here is a
typical GMAIL response telling that you need to use
authentication : “530, response: 5.7.0 Must issue a
STARTTLS command first”.

In a departure from the original intended use for error 530,
one of the most irritating misuse of SMTP response 530 is
its use to either indicate that your server has been
blocked by the recipient’s server or that the recipient’s
mailbox does not exist. And to make matters worse, the
explanation text attached to the error is totally misleading.
Judge for yourself – how would you ever suspect that
“SMTP error 530 : The message cannot be delivered
due to a configuration error on the server. Please
contact your Administrator.” either means that the
recipient’s server has actually blacklisted your server
or that the recipient’s mailbox does not exist ? Mad !!!
This misuse of error 530 is a fault of the outgoing
mailserver, almost always your own ISP’s server which
should return a 554 or similar error (for example : “554 this
user doesn’t have a Yahoo.com account”), but which
instead returns a 530 error.

SMTP Status Codes and Error Messages from Error 523

SQLServerF1

SMTP status code – 523 – The Recipient’s mailbox cannot receive messages this big
(also called SMTP Error 5.2.3)
SMTP Status 523 : This error will be received when the
total size of the message you have sent (ie: message + all
of its attachments) exceeds the size limits on the
Recipient’s server. Many companies implement the good
practice of configuring their servers with limits on the size
of emails they can receive to prevent their systems running
out of space as a result of a spam attack where the spam

emails contain large attachments, or as a result of valid but
not very technically savvy senders sending enormous
scans (through not knowing that scanning at 1200dpi
rather than the usually perfectly usable and acceptable
300dpi, will create humongous attachments).

Check the size of the email you sent, and, specifically, the
size of the attachments you included, and consider splitting
your email into smaller emails. If that does not work, check
with the Recipient the maximum size of email they can
receive, and if that is still prohibitive then consider FTP
arrangements between you and the recipient.
SMTP Error 523 is often a secondary SMTP error code
rather than a primary error code, as in the following
examples : “SMTP Error 450 5.2.3 Message Size greater
than allowed by Remote Host” or “SMTP Error 552 5.2.3
Data size exceeds maximum permitted” or “SMTP Error
552 5.2.3 Message exceeds maximum fixed size”, and so

SMTP Status Codes and Error Messages from Error 513

SQLServerF1

SMTP status code – 513 – Address type is incorrect (most mail servers) or Relaying denied or Authentication required (a small percentage of mail servers)
(also called SMTP Error 5.1.3)
SMTP Error 513 : This status code (from the sender’s
mail server) is usually symptomatic, in an Exchange +
Outlook environment, of the user’s Outlook Contacts
having been imported from another system or PST and
where some of the addresses are not defined correctly.
Or, in any environment it is simply that the end-user simply
did enter the email address completely wrongly, such as
copying it from a website and not replacing “at” with “@”,
e.g. : John.DoeatUCLA.edu (which should have been
John.Doe@UCLA.edu), or John.Doe@UCLA.edu” (“,
quotes, is not allowed in email addresses and is often
included in error as a result of copying and pasting an
email from somewhere).

The user should check all the recipient addresses in the
email, including those that were inserted from Contacts.
Note : the SMTP reply code 5.1.3 is often a secondary
reply code. Some mail servers, for example, might reply
“SMTP error 501 5.1.3 Invalid address”, or “SMTP error
553 5.1.3 User address required !”, or “SMTP error 501
5.1.3 Bad recipient address syntax”, or “SMTP error 513
Relaying Denied – Can not send e-mails to some
addresses”, or this excellently informational Exchange
Server 2007 error (the whole error message is in green
below) :

”SMTP error 550 5.1.3 STOREDRV.Submit; invalid
recipient address.
Delivery has failed to these recipients or distribution lists:
The format of the recipient’s e-mail address isn’t valid. A
valid address looks like this: username@microsoft.com.
Microsoft Exchange will not try to redeliver this message
for you. Please check the e-mail address and try sending
the message again, or provide the following diagnostic text
to your system administrator.
5.1.3: The format of the recipient e-mail address is not
valid. Valid SMTP e-mail addresses can contain only
letters, numbers, hyphens, periods, and only one @
symbol. Troubleshooting: Verify that the SMTP address of
the recipient is formatted correctly and resend the
message.”
————–
SMTP Error 513 is also used by a small percentage of
mail servers to indicate a completely different error, namely
that you need to authenticate to the mail server before
being able to send your message (SMTP authentication).
A typical error message might be : “SMTP error 553
Authentication is required to send mail as
username@ispdomainname.com”.
In such cases you simply need to configure your mail
server, or your email program to send emails with SMTP
authentication.

SMTP Status Codes and Error Messages from Error 512

SQLServerF1

SMTP status code – 512 – The host server for the recipient’s domain name cannot be found (DNS error)
(also called SMTP Error 5.1.2)
SMTP Error 512 : This SMTP reply code is received
when one of the servers on the way to the destination is
unable to resolve the domain name of a recipient email
address. Said differently : one of the servers on the way
to the destination, including your server or your ISP, has a
DNS problem or, possibly correctly, does not like one of
the email addresses in the message’s TO, CC, and BCC
fields.

The first check you should perform to resolve a 5.1.2 reply
code is to check all the recipient email addresses for
incorrect domain names (misspelt domain names, or,
maybe, totally non-existent domain names) – remember,
error code 512 is very specifically an error with the
domain name of one of the recipient email addresses.
You can call the recipient(s) or use the WHOIS tool of The
Ultimate Troubleshooter. If all the recipient email
addresses check out as regards the domain part of the
email addresses, then one of the servers on the way to the
recipient(s) has DNS problems – usually this will be one of
the first 2 servers in the chain, your own mail server (or
your network) or your ISP’s mail server.

Examples of typical SMTP error 512 messages : “5.1.2 –
Bad destination host ‘DNS Hard Error looking up domain”,
or “SMTP Error 550 5.1.2 Host unknown – host cannot be
found”, or how about this fantastically informative error
message “5.1.2 The message could not be delivered
because the recipient’s destination email system is
unknown or invalid. Please check the address and try
again, or contact your system administrator to verify
connectivity to the email system of the recipient.”.
In summary : most SMTP error 512 conditions are
caused by misspellings of the domain name part of a
recipient email address. However, with the proliferation
of spam, error 512 is also often encountered by automatic
“out-of-office” replies to junk mail because the domain
names used by junk mail are often bogus domain names.

Above are list of SMTP Errors Codes and Status Codes along with Error and Warning messages from Error 512 received while performing certain operation against mail server applications or related products.

What are SMTP Error Messages?
Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission. SMTP protocol is used for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP.

In general, each SMTP error contains the following information:
• The SMTP Status Code or SMTP Error Codes or SMTP Reply Codes
• The message text. This text is usually returned with the Error code. Some messages employ word substitution, where the word substituted represents the system-replacement of a term more specific to the occurrence.
• An explanation of how the error may have occurred.
