no fixup protocol smtp 25 IIRC. That, and the exact place where the pix's

Also in that "Mailguard" (the horribly sucky mail firwall PiX sets up) breaks
ESMTP, allowing only SMTP. More security by obscurity.

It was with great difficulty that I persuaded one of our clients from
sticking a mailguard in front of a perfectly secure set of sendmail and exim
boxen. I still thank my stars, and ROFL at the dirty looks their ahem...
"security consultant" was giving me. He was all in favor of scrapping the
sendmail / exim (on freebsd and slackware) for bloatus jokes, which is saying
a lot ...
