Re: Cannot send mail to "some" domains



Just a few questions:

The addresses you are trying to send to, are they external addresses?

Have you tried performing the smtp test from your Exchange server to the
domain that you are having problems sending?

Does your Exchange sit in a DMZ? Do you use a smart host or have you
defined the FQDN for the Exchange server?

thx,

Jim

Jim,

Thanks,

I was able to telnet to my server and send email to myself as well as my
personal account via telnet. I still received errors sending this way to the
same domains I was having issues with using OWA or Outlook. I am either
getting the following errors: 5.1.1 or 5.4.6

I deleted the contact in AD for the one user that received the 5.4.6 error
and recreated it. I then received the 5.1.1 error the first few times I
tried to send and then eventually went back to the 5.4.6 error.

HELP PLEASE

The following has always worked for me when testing:

1. Telnet to server host (FQDN) or IP using port 25
2. type helo (sometimes you may need to type the domain name in addition to
helo)
3. mail from: email address <Enter>
4. rcpt to: email address <Enter>
5. data <Enter>
6. Subject: whatever <Enter>
7. Type message <Enter>
8. <Enter>
9. .
10. <Enter>
11. quit <Enter>


hope this helps,

Jim

Susan,

I must be doing something wrong because it keeps failing and I tried to
connect to other mail systems that I know are up and running and can't
connect there either. I am using:

telnet mail.domain.com 25

Is that correct?

session? sometimes you can get more information that way...

We recently performed an Exchange migration from 2000 to 2003 on new
hardware. We can send internal email with no issues. I have not been
told
of anyone not receiving inbound emails at this time. But I have had 2 or
3
people say that they can no longer send emails to particular domains. I
have
seen two different types of Error Messages returned to the users inbox. I
have tried sending from different accounts logged in on Outlook or OWA and
I
get an immediate Undeliverable message in my inbox. I can however send to
the addresses from my personal email account outside. When I go into the
Event Viewer on my Exchange Server I do not have any NDR listed or errors.

Error 1 :
Your message did not reach some or all of the intended recipients.

Subject: test
Sent: 3/12/2007 10:11 PM

The following recipient(s) could not be reached:

user@xxxxxxxxxx on 3/12/2007 10:11 PM
The e-mail account does not exist at the organization this message was
sent to. Check the e-mail address, or contact the recipient directly to
find
out the correct address.
<newmailservername.domain.com #5.1.1>

Error 2:

user@xxxxxxxxxxxxxx on 3/13/2007 12:42 PM
The destination server for this recipient could not be found in Domain
Name Service (DNS). Please verify the email address and retry. If that
fails,
contact your administrator.
<oldmailservername.domain.com #5.4.0>

Any help would be appreciated.

Regards
