Using msmtp as a Lightweight SMTP Client

"Last week, I covered OfflineIMAP to sync IMAP for use with Mutt or other applications. Continuing with that theme, I want to talk about another tool I use with Mutt to handle the opposite problem -- actually pushing mail to an SMTP server. Let's take a look at msmtp.

"Mutt is a fantastic mailer for admins, but it doesn't do SMTP. It expects that to be done by an Mail Transport Agent (MTA). Usually, this is something like Sendmail or Postfix, and that makes sense when they're living on the same system. But it comes to running Mutt on a laptop or desktop, many admins have better things to do with their time than to set up a full-blown MTA. You may not even be running your own mail services in-house, so why dust off the Sendmail or Postfix documentation just to set up a personal MTA?

"Actually, you can configure msmtp on the user level or the system level -- so if you want to set up a very lightweight Sendmail replacement for a system, msmtp should do the job."
