Hi,

Similar to my question earlier about an all-Perl HTTP server,
I have asked myself whether there is a production-quality all-Perl
mail server.  This would allow you to write code in Perl to 
process mail messages without forking a Perl interpreter per
message.

If anyone has more input, I'd like to know.

This is what I've found so far (and it appears to work with qmail).

There is a drop-in replacement called "qpsmtpd" for a certain server
within the qmail server suite (qmail-smtpd) which has been written 
in Perl (thanks to Ask Bjoern Hansen).

I know this really wasn't your question, but this was an interesting
discovery that was relevant specifically to your mail delivery problem.

P.S. There is a mail server written entirely in Java, called "James",
     hosted by Apache.  There ought to be one for Perl.
