From the doc: 'This is the smallest e-mailer that exist. It gives to user complete control over sending e-mail! Mailer v1.25 use the file 'mailer.dat' where user can store some data that he need to use often. Mailer v1.25 supports attachments. This can be an anon-mailer, too! And a bomb-mailer :) It is very good for scanning SMTP servers.'
