I'm considering replacing qmail-smtpd with qpsmtpd (and keeping
everything else the same, including vpopmail).
I'm under the impression it is as simple as replacing qmail-smtpd's run
script (tcpserver) with a qpsmtpd run script.
qpsmtpd can be used as-is, or with PPerl (persistent perl) or with
mod_perl2 (using Apache2 to handle very high concurrency).
Has anyone else already tried doing this? Any comments?
