Just looked around a bit to send an email to a list (an
external address) when a bug is set to a specific
status (like "done-cbb" or "resolved").
From what I've understood so far I can't directly use
roundupdb.send_message() as a msg is needed.

So I want to create my own message for this issue.
It would be nice to have a more general method which is
called
by send_message() to create everything that is needed
to send an email related to one issue, but does not
need a msg.

Alternatively I would appreciate an example which
solves my task
if it is possible using a temporary msg object.
