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>"
<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 AUTH LOGIN PLAIN

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).
