Easy way to forward all email

  • 772

Is there an easy way to install a MTA on Ubuntu and forward all email to a different remote email box? Only want to forward local email and looking for something dead simple. Thank you!

Clarification:

I see that ssmtp and nullmailer are suggested, but I need something (just a) little more clever. I have one machine (machine.domain1.com) where I want local mail to be delivered at [email protected] and I want it delivered through direct connection to mx.domain2.com

So when I do mail root on machine1.com it should get forward to [email protected]. Issue with nullmailer and ssmtp is that forwarding is done to mx.domain2.com but mail is delivered with a RCPT TO set to [email protected] and I want the RCPT TO set to [email protected]

Possible with a simple solution or do I need to digg into postfix or exim for this?

    There's certainly no shortage of MTAs in Linux, nor in Ubuntu. As the most full-featured (and possibly overblown) solution, you can use postfix to relay emails to a provider - i.e. all the emails it receives will be sent via that SMTP server. Here is a tutorial with details for Google Mail.

    A more lightweight, and more simple alternative is nullmailer, although I'm not sure if it is capable of using all the secure transport methods required for Google Mail.

    Finally, the easiest solution seems to be ssmtp. The setup is described here.

  2. It doesn't get much simpler than nullmailer Install nullmailer . Although the mail will have to be sent to real addresses as nullmailer only forwards to a smart MTA.
