I'm looking for a simple smtp daemon, that supports aliases (due to issues with daemons, that refuse to send emails to anyone else than root).If you don't know msmtp, then basically, I just want to configure an external SMTP that will handle all mail delivery.
msmtp alternative that understands /etc/aliases
smtp;email
msmtp seems to understand aliases, see http://msmtp.sourceforge.net/doc/msmtp.html#aliases . It seems just a matter of correct configuration.
