Software configuration for msmtp for Sending emails. See also Ansible

msmtp is an SMTP client.

In the default mode, it transmits a mail to a SMTP server (for example at a free mail provider) which takes care of further delivery. To use this program with your mail user agent (MUA), create a configuration file with your mail account(s) (in /etc/msmtp.conf) and tell your MUA to call msmtp instead of /usr/sbin/sendmail.
