We were just 'gifted' by some lovely Email from a fellow who wished our users
to have university degree in a few weeks.
The header on his Email looks like:

Is an utterly null From line allowed?
This is with a standard 1.03 Qmail.
>From a normal modem, this guy has managed to get our queue to:
bash-2.02# /var/qmail/bin/qmail-qstat
messages in queue: 83261
messages in queue but not yet preprocessed: 4
(and this is with a rather powerful multi processor sparc)
What can be done about this sort of thing? It's really annoying that one
idiot with a modem can destroy a rather large Qmail system.
(dual processor ultrasparc, 512Meg RAM, 50Gig RAID)
(yes, I lock out his IP, but he just dials in and gets another one)
