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.

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.

example /etc/msmprc

#logfile   /var/log/mail.log

Use startTLS on port 587


port 587
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt


host mailserver.net
from Sender Name <user@maildomain.com>
auth on
#auth plain
#auth scram-sha-1


user user@maildomain.com
password YourUnGuessueAblePass


Set a default account


#account default : outlook
