Automatic email forwarding #email #postfix #mail #emailclient #ssmtp

How do I configure #sSMTP to change both, the FROM and the TO field?
mailer.conf refers to ssmtp for #sendmail, and is used by #CRON. Unfortunately, from- and to-fields in those mails only contain the local username and can not be delivered by the external mail server. Using mail(1) from the CLI does respect all the aliases from mail.rc and mails get delivered.
What's a proper way to setup system #mail with external #SMTP on #FreeBSD? Changing #MTA would be ok, if needed. #Email #followerpower

#FOSS advice required!
#rasbperrypi
#debian
#manjaro
#freebsd
#openbsd

I have been running #ssmtp on raspberrypi as I need to get mail off the box. However, I see notes on debian that is is now unmaintained but still available as a package.

I've looked at #msmtp as an alternative and also #dma. both seem to work well

I only need a method of getting mail off the box so I don't need a full smtpd like exim, postfix etc.

What's the feeling for a futureproof, supported transfer agent?
TIA
