Our fast host rejects most spam, quickly about it, and forwards mail

only client to be generous about timeouts.
But, in effect, that's an 'accept and bounce later' system.
Nope. It rejects about 99.6% of spam messages. The remaining 0.4% are
accepted. (Those 0.4% aren't actually bounced in our setup, but for the
sake of argument, let's pretend they are.)
Everyone here seems to be saying that's a bad thing :) (faked sender
email addresses etc)
Surely, if you're going to be able to reject a message at any time,
you should do it at the initial entry point so that faked sender
email addresses have less impact.
As long as you reject the vast majority of them at the initial entry
point, the rest doesn't matter. It's an annoyance, but not significant.
So you can e.g. accept the mail after ten seconds, if you haven't found
a reason to accept or reject before then.
