I can't implement this until I can get reliable code for all of
         sendmail - Me
         Exim - Tony Finch / Nick
         Postfix - done already
         ZMailer - Mariano
         Qmail - OpenComputing Project

The above are suggestions of who I would really like to write what, as and
when they have time. I am not an expert in all the MTAs and only wrote
support for 2 of the 5 myself.

Any chance of some help here people?
Many thanks, it is all appreciated by everyone!
