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/password in msmtprc)

    Edit: I think it’s actually the auto_from option which interests you. Check the msmtp manpage

      In 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.
