Because if you implement callbacks, you're most likely not refusing <>
What I already discussed with Philip was to have callbacks that first do
MAIL FROM: <>
fail null mail from
or
RCPT TO: <dest>
fail null mail from
RSET
MAIL FROM: <postmater@mysite>
RCPT TO: <dest>
If you do that, it's reasonably safe.
I think Philip agreed to it (it's been a while, so I might be wrong),
but I guess it hasn't been implemented yet (I haven't had any time to
work on this myself recently)
