554 Sorry, no mailbox here by that name

[rharmstr]

We have been having a problem sending email using Outlook 2003 on
Windows XP pro machine from a pop3/smtp mailserver where the users ar
getting the error:

"Task 'user@<mydomain.com> - Sending' reported error (0x800CCC0F):
'The connection to the server was interrupted. If thi
problem
continues, contact your server administrator or Interne
service
provider (ISP). The server responded: 554 Sorry, no mailbox
here by that name. (#5.1.1)'"

I turned on logging in Outlook 2003 which returned:

The email message remains in the outbox and is not sent to any of th
recipients.

We have not been able to find a resolution to the problem, however, w
did identify 2 scenarios where this occurs. 1) when one of th
recipients did not exist on our domain as a valid email address (i.e
user2@<mydomain.com>) and 2) when an address at the "Netzero.com
domain is one of the recipients.

I was able to re-add the invalid address for our domain, which appear
to have corrected the first scenario. For scenario 2, I can change th
sending account to my ISP and the mail message gets bounced a
undeliverable.

What we cannot determine is why the send from our domains smtp serve
does not send the message to any of the recipients.

Any idea's?

Best regards,

The 554 error occurs after issuing the RCPT TO command (and that is what
tells your mail server where to deliver your message, not any of the
headers within the message that are sent in the DATA command). The only
way that your mail server knows that the mailbox doesn't exist during
YOUR mail session to send your message (and because it hasn't connected
yet to the receiving mail host) is because you are trying to send to a
recipient that uses the same domain or e-mail service; i.e., you are
sending from the same domain to which you are sending the mail to the
recipient. If the recipient were on a different domain, it would not be
known that the recipient's mailbox existed or not until your mail server
accepted your message and then attempted to connect to the recipient's
mail host for a mail session with it to get that receiving mail host to
accept the message.

The reject is occurring immediately during your mail session. Looks
like you are trying to send from <you>@<yourdomain> to
<them>@<theirdomain> and yourdomain and theirdomain are the same. That
is why the sending mail host can look up immediately to see if the
recipient's mailbox exists or not (because sending and receiving mail
hosts are the same or within the same e-mail provider).

Do the 554 error ever occur when you send e-mail to a recipient on a
*different* domain? Does the value in the RCPT TO command actually
comprise a valid e-mail address? Even if sending to a recipient on the
same domain, you will still need to specify the domain portion of their
e-mail address (i.e., you cannot send to "johndoe" without specifying on
which domain to look for the johndoe-named account). Did you check for
leading or trailing spaces in the string specifying the recipient's
e-mail address, or for illegal characters?

The email message remains in the outbox and is not sent to any of the
recipients.

Because your sending SMTP server rejected your mail send. You sent to
an internal recipient (i.e., within the same e-mail service) or the
string specified for the recipient's e-mail address is not a valid
e-mail address.

For scenario 2, I can change the
sending account to my ISP and the mail message gets bounced as
undeliverable.

Further proof that the e-mail address that you are using is not a valid
e-mail address or there is no such account that matches the username in
the e-mail address.

The reject is occurring immediately during your mail session. Looks
like you are trying to send from <you>@<yourdomain> to
<them>@<theirdomain> and yourdomain and theirdomain are the same.
That
is why the sending mail host can look up immediately to see if the
recipient's mailbox exists or not (because sending and receiving mail
hosts are the same or within the same e-mail provider).

For one of the attempts this is true. I sent to an address that i
hosted by the same provider and one that is not.

The email addresses being sent to may have become invalid, but if no
on our domain, they should be passed on to the receiving domain an
returned as undeliverable. Instead the smtp server is rejecting th
address and causing Outlook to stop.

These are the exact steps and responses from Outlook.

So what anti-virus and/or anti-spam products do you have running? Have
you tried temporariliy disabling them?

Since you are using your own SMTP server, have you checked with your ISP
that they will permit you to send SMTP traffic across their domain to
connect to an SMTP server on a different domain? As an anti-spam
measure, many ISPs now require that all SMTP traffic from their
customers must target that ISP's own SMTP server. Also, since you are
running your own mail server, does your domain's nameserver have valid
MX records for your mail server (since some receiving mail hosts will
use the MX record to check if a sending mail host is a valid one
recorded for that domain). Some receiving mail hosts will even reject
mail connects from sources without a valid A record (because they want
to do a name lookup on the IP address). If you switch from using your
own SMTP server to using the one provided by your ISP, do you still have
the reject messages (during your mail session with their SMTP server)?

I am running Norton internet security 2005. I have disabled all emai
scanning, anitvirus and anitspam checking and retried. The same 54
occurs and does not pass through the SMTP server. I have had my domai
and email running through this server for nearly 5 years.

I can use my ISP's SMTP server and the messages are sent out and a
undeliverable email is sent back to me. This is what I would expec
any SMTP server to do, but it is not happening. I am sure this is no
an outlook problem now. But need to test using express and a non M
email client.

My ISP does not require using their SMTP server as I am able to send t
valid email addresses on any domain. This has never been an issue.

I have asked the email hosting provider for more assistance as it doe
not seem right that the SMTP server is rejecting the address if it i
not from the same domain
