What simpler mail server can I use instead of postfix?

  • 772

I have a home server which needs a mail server for error messages, mostly.

I used postfix but I find the features/complexity compromises not optimal for my home server: there are tens of lines to check/configure, stunnel to install for TLS, ...

What simpler mail server with TLS support can I use, that is also packaged by Canonical? I'm going to only use an external relay server provided by my provider.

mail-server

    A simple relay-only mail transport agent is nullmailer.

    There is a good configuration guide here: http://www.troubleshooters.com/linux/nullmailer/

    That configuration guide is old enough that it omits one important configuration file: /etc/nullmailer/allmailfrom. Put just the email address you want the mail to be sent From in there. This helps tremendously when configuring various applications to send mail.
