Greetings master postfixers,
I am trying to solve a forwarding problem. I have two separate amavis
instanceson my edge MX that each do spam-checking: one incoming

Varad,
I may be talking out of turn as I am fairly new to Postfix, but I think
we need to distinguish between a *practical* risk and a *theoretical* risk.
Theoretically, any software that runs as root, sufficiently attacked,
could be used to compromise an entire system. The sufficient attack
at throttling or
quota limits based on usage statistics (assuming overuse is the real
concern). If this were a standard need, I imagine there would be a
canned, comprehensive, iron-clad solution.
