You forgot to mention what version of OpenBSD you are using ?

I don't like the idea that because procmail produces a corrupt line that
comsat doesn't understand, smtpd should have a special case and parse an
aliases mapping or forward files looking for the string "procmail".

If you're running current, you might want to try:

"|exec /usr/local/bin/procmail -f %{mbox.from} || exit 75"

in case it helps procmail produce a correct sender.

Can you provide me with the corrupt line procmail includes so I can
check if it is invalid indeed ?
