Last week I was at YAPC and attended mock's talk about building an SMTPd in mod_perl2/apache2. But before going I wanted to be able to build something like that for myself. So I wrote Apache:Qpsmtpd - a mod_perl2 handler that embeds Qpsmtpd (http://smtpd.develooper.com/)
http://www.sergeant.org/Apache-Qpsmtpd/
It seems to mostly work, though if you want to play with it you'll need the current cvs of qpsmtpd. It's about 3 times faster than the qpsmtpd-forkserver that ships with qpsmtpd.
Someone posted privately asking why I thought it was faster, but my reply to them bounced (broken anti-spam system I think) so I'll reply here:
I think it's faster because it pre-forks. qpsmtpd-forkserver is just naive - it forks once per connection. Plus I guess Apache does the I/O for you, though I don't think that's really gaining me much - consider the overheads of the bucket brigade vs Perl's readline.
