If the server is also acting as an IMAP or POP3 server you probably need to set up your virtusertable file as well.
I set up Sendmail Server with a domain on the FC3 linux server and works fine. Now I want to add anoather domain name to it.
This is what I did:
1-I add two line to The /etc/mail/local-host-names File:
2- I add online The /etc/mail/virtusertable file:
# cd /etc/mail
and restart sendmail.
when I send email to: email@example.com
I got this message:
The e-mail system was unable to deliver the message, but did not report a specific reason
