Additionally, I've started seeing (because I'm monitoring the account
which catches rubbish at work) autoreply messages being rejected by
PRVS/BATV enabled systems.

Presumably this is because a lot of autoreply generators use a null
envelope sender, so are processed as bounces in order to prevent mail
loops. Since not all null envelopes are bounces (although the majority
are) this is a slight flaw in the design of BATV. Ho hum.

PS yes, I understand that there are pseudo-religious views on
autoresponses...
