Blank emails

[Jozef Hitzinger]

I've seen these a few months ago quite a lot, now it ceased. If it appears
again in quantities that'll be a problem, I plan to patch MTA to refuse
mail without headers (fisrt line in DATA section is empty) during SMTP
phase.

I know it's not strictly following the RFC, but in a world where so many
mails abuse that RFC by forging headers, it's one of the ways to ease
things for the us before we get some SMTP fix/replacement. It's about how
many legitimate mails without headers you expect to get (me zero).
