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 what I’ve used before.

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.

Looks like to setup OpenSMTP as a relay, you are recommended to use
procmail, which is itself unmaintained.https://wiki.archlinux.org/title/OpenSMTPD
Still msmtp lacks one feature that I had to workaround: It wasn’t properly handling cron mail that was generated to a bare address like
rootortest. I solved that by writing an sendmail wrapper which rewrites the input just before it’s handled to msmtp.https://github.com/marlam/msmtp/issues/98

Ah, thanks
ssmtp is also my go-to for this. Or dma (DragonFly Mail Agent) - if available - which provides a queue in case the delivery to the smarthost fails. But as it’s not running as a daemon (saving resources), so you have to setup a regular cronjob to process the queued messages.
I use ssmtp as well for a simple sendmail replacement. It takes over the sendmail command, doesn’t open any ports. You configure it for the domain you want and tell it what server to send everything to and it works.
