Sendmail error: user unknown dsn=5.1.1
I recently was able to get sendmail working on our Debian server. However, there is a small problem. I can send email to:
but NOT to:
<jsmith at DOMAIN.com>
I get this error: stat=User unknown and dsn=5.1.1 in /var/log/mail.log
We also have an alias domain (jsmith@ALTDOMAIN.com) that works fine.
How can I get <jsmith at DOMAIN.com> to work? Thanks!!
Here is our configuration:
Debian Linux with sendmail
MS Server with Exchange
When we send email from computer 1, it goes to computer 2 (the smart host). However, if the email address we use is (jsmith@DOMAIN.COM), it sends it to computer 1. I saw the test email in /var/mail/jsmith.
How can we get it to send from computer 1 to computer 2 while specifying DOMAIN.COM?

Try to send mail local and outside, paste the mail error log...
