ruby-mail - 2.7.1+dfsg1-2 main

The purpose of this library is to provide a single point of access to
handle all email functions, including sending and receiving
emails. All network type actions are done through proxy methods to
Net::SMTP, Net::POP3 etc.
.
Built from experience with TMail, it is designed to be a pure ruby
implementation that makes generating, sending and parsing emails a no
brainer.
.
Finally, Mail has been designed with a very simple object oriented
system that really opens up the email messages you are parsing, if
you know what you are doing, you can fiddle with every last bit of
your email directly.
