Recommendation for outgoing-only SMTP server

markstos@lemmy.world to Selfhosted@lemmy.world – 31 points –

I'm looking for a simple sendmail replacement to receive local mail, such as from cron and service failures and forward it to on to a real SMTP server.

I have used msmtpd successfully but thought I'd ask if folks have other solutions they like.

ssmtp is unmaintained.

msmtp is the recommended successor. The Arch wiki recommends also considering OpenSMTPD, which I haven't looked at yet.

I just started using OpenSMTPD as a backup relay and it seems to work for that. Very lightweight and easy to set up.
