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: jsmith@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@DOMAIN.com to work? Thanks!!
