====== MTA - Mail transfer agents ======

====== Exim ======
small mail transfer agent listening on port 25 - useful on local server
sometimes it crashs.. ^^

setup a correct (dns resolvable) hostname:
  dpkg-reconfigure exim4-config

mailservers may block temporary dyndns IPs or move them to spam!

remove all frozen messages from mailq:
  exim -bp | exiqgrep -i | xargs exim -Mrm

not even a daemon. it just forwards mails. very simple and useful for websites and system to just send mail.

  # See also https://support.google.com/mail/answer/78799
