When the message is in limbo (waiting for delivery to [EMAIL PROTECTED]), is it in the local or remote queue on company1?
Try another test to find out. This will narrow things down a bit.

Sunday, I sent several test messages from [EMAIL PROTECTED] to
[EMAIL PROTECTED] and finally got the "undeliverable" message back
yesterday.

Your message did not reach some or all of the intended recipients. Subject: RE: [Fwd: Test mail] - test received Sent: 9/11/2006 3:40 AM The following recipient(s) could not be reached:
  [EMAIL PROTECTED] on 9/13/2006 3:49 AM
  Could not deliver the message in the time limit specified. Please retry or
contact your administrator.
<company2.com #4.4.7>
Notice that the error message is now coded #4.4.7

Could it be a dns issue? Perhaps I should remove any reference to
company2.com from Bind and simply enter the exchange server name & ip in
/etc/hosts?

Thanks,
Ron


Make sure that neither domain is in /var/qmail/control/locals

I'm having trouble chasing down the source of an error message that I'm getting. There are two domains behind a single firewall.

Company1.com - hosted on the qmail toaster.
and
Company2.com - hosted on an exchange 2003 server. But whose mail gets passed through the qmail toaster with a simple entry in /var/qmail/control/rcpthosts and /var/qmail/control/smtproutes.

company1.com can receive mail from any domain EXCEPT company2.com. BUT company1.com can send to company2.com

When I attempt to send an email from [EMAIL PROTECTED] (via
outlook/exchange) to [EMAIL PROTECTED] I receive periodic error messages advising me that sending is delayed.

After about a day, I get an undeliverable message that says:
"There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator.
<company1.com #5.5.0 smtp;550-"The recipient cannot be verified. Please check all recipients of this>"

There isn't anything in /var/log/qmail/smtp/current So, I tried to telnet to the company1.com mail server hoping to see some other sort of
output.
When I telnet to mail.company1.com 25 (from anywhere) I get:
EHLO mydomain.com
250-Greetings from the company1.com mail server. Now Go Away! (my own
smtpgreeting)
250-STARTTLS
250-PIPELINING
250-8BITMIME
250-SIZE 419430400
250 AUTH LOGIN PLAIN CRAM-MD5
MAIL FROM [EMAIL PROTECTED]
250 ok
RCPT TO [EMAIL PROTECTED]
511 sorry, you must specify a domain <#5.1.1 - chkuser>


I'm completely stumped, though it's got to be something simple (user error being most common).
