In the dim, distant past when 'sendmail' was the only MTA, people who
worried about 'security' ran "smtpd" (IIRC) on port 25.

It understood the SMTP protocol but nothing more & wrote files to a
directory, from whence sendmail picked them up.

That, plus a script to hack the subject line & resend the file would
fulfil your need/requirements.

I've had a quick look, and cannot find it. My Google Fu is ebbing :-(
The term 'transparent proxy' came up a few times.

There is a lightweight server:

BUT, qmail-smtpd says it does this sort of thing.

The Anti-Spam Proxy seems over kill:

An SMTP daemon in PERL. Who'd have thought the swiss-army chainsaw tool
for Admins could do that :=]

A random page on Perl Net::SMTP
