Sendmail

Configuring Virtual Users

• Create a file called /etc/mail/virtusertable.txt
• Edit the contents of the file

virtualuser@mydomain.org                   someexternaluser@otherdomain.com

• Deploy the above file using the following command

makemap hash /etc/mail/virtusertable < /etc/mail/virtusertable.txt

• This above creates a virtual email address and forwards mail to that address to the specified address.

Relay outgoing mail through a relay server

This scenario is useful if the ISP has a firewall on outgoing SMTP connections (telnet foo 25 gives a "Connection refused"). http://www.ozzu.com/ftopic29690.html
