I recently was able to get sendmail working on our Debian server. However, there is a small problem. I can send email to:

jsmith@DOMAIN

but NOT to:

[email protected]

I get this error: stat=User unknown and dsn=5.1.1 in /var/log/mail.log

We also have an alias domain ([email protected]) that works fine.

How can I get [email protected] to work? Thanks!!
 


Update:

Here is our configuration:

computer 1
Debian Linux with sendmail

computer 2
MS Server with Exchange
DOMAIN.COM

When we send email from computer 1, it goes to computer 2 (the smart host). However, if the email address we use is [email protected], 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?

Thanks!
