SMTP plugin for MUAs

msmtp – An SMTP client

msmtp is an SMTP client that can be used as an “SMTP plugin” for Mutt and probably other MUAs mail user agents. It forwards mails to an SMTP server for example at a free mail provider which does the delivery. To use this program, create a configuration file with your mail accounts and tell your MUA to call msmtp instead of /usr/sbin/sendmail.

Features include

* SMTP AUTH methods PLAIN, LOGIN and CRAM-MD5
  and DIGEST-MD5 and NTLM when compiled with GSASL support
* TLS encrypted connections
  including server certificate verification and the possibility to send
   a client certificate
* DSN Delivery Status Notification support
* IPv6 support on systems that support it
* support for multiple accounts
* sendmail compatible exit codes which most MUAs understand.
