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:
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.
- install msmtp and msmtp-mta
- when using cron , you might take a look here to have a real from header
example /etc/msmprc
#logfile /var/log/mail.log aliases /etc/aliases.msmtp #user #password # 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 <> auth on #auth plain #auth scram-sha-1 user password YourUnGuessueAblePass # Set a default account #account default : outlook example /etc/aliases.msmtp
mailer-daemon: postmaster: nobody: hostmaster: usenet: news: webmaster: www: ftp: abuse: noc: security: # Send root to Joe and Jane root: # Send everything else to admin default:
