Package procmail

https://github.com/BuGlessRB/procmail

Procmail can be used to create mail-servers, mailing lists, sort your
incoming mail into separate folders/files (real convenient when subscribing
to one or more mailing lists or for prioritising your mail), preprocess
your mail, start any programs upon mail arrival (e.g. to generate different
chimes on your workstation for different types of mail) or selectively
forward certain incoming mail automatically to someone.
