trivial transparent SMTP proxy

About smtpprox

smtpprox is a trivial transparent SMTP proxy, an SMTP server and client combination. It uses its own SMTP server and client modules which are designed to expose every step of the protocol dialogue to the calling program, which provides for the greatest flexibility in hooking in envelope and content controls and scanning.

For efficiency reasons, it pre-forks and serves from a pool of servers, Apache-style.
