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.

You can definitely replace senders with correct mail addresses for relaying through SMTP servers that expect them (this is what I do):
# /etc/msmtprc account default ... host smtp.gmail.com auto_from on auth on user myaddress password hunter2 # Replace local recipients with addresses in the aliases file aliases /etc/aliases# /etc/aliases mailer-daemon: postmaster postmaster: root nobody: root hostmaster: root usenet: root news: root webmaster: root www: root ftp: root abuse: root noc: root security: root root: default www-data: root default: [email protected](the only thing I changed from the defaults in the aliases file is adding the last line)
This makes it so all/most system accounts susceptible to send mail are aliased to root, and root in turn is aliased to my email address (which is the one configured in
host/user/passwordin msmtprc)Edit: I think it’s actually the
auto_fromoption which interests you. Check the msmtp manpageIn the issue I linked, the msmtp author makes a distinction with changing the envelope recipient, which msmtp can do, with rewriting the email headers like “To”, which msmtp does not do.
