Two years ago I started to write my own mail library. Initially I
only thought of filtering mails. Soon I started to generate mails,
too. In the meantime I filtered about 100,000 mails and I generated
about 25,000.

If you like to have a look at it, please do something like:

  gem fetch --source http://bertram-scharpf.homelinux.com/bs_gems/ cropmail
  fetch http://bertram-scharpf.homelinux.com/bs_gems/cropmail-1.6.gem

It isn't documented very well because nobody uses it but me, but
it is thoroughly tested and it is very easy to use.

Below I will cite some sample code how I generate a mail.

I would be pleased if you like it. In case you don't I wish you
good luck anyway.

  m.push attachment

  m.sendmail
