msmtp project is an SMTP client.
In the default mode, msmtp transmits a mail to an SMTP server (for example at a free mail provider) which does the delivery.
To use this program with your mail user agent (MUA), create a configuration file with your mail account(s) and tell your MUA to call msmtp instead of /usr/sbin/sendmail.
msmtpqueue is a pair of very simple shell scripts that allows you to "queue" mails and send them all at a later time (useful for dialup connections: write your mails offline and send them when you are online).

msmtp is released under the GPL with the additional exemption that compiling, linking, and/or using OpenSSL is allowed.
