it does, if you

server_prompts = $pid.$tod_epoch@$whatnot

there is a BIG difference between putting a *macro* like above (which
is expanded *once* when the child is spawned) and this one i think you
did. the pids wouldn't have been the same otherwise.

i can't find any logical explanation for that, except the one outlined
above. granted i never did negative tests ;) (which is a bad thing,
actually, i *strongly* advise everyone do them especially when setting
up authenticators. i wonderfully run an open relay for a good while,
'cause i screwed up the auths, and they authenticated everyone. i
positive-tested it, it was ok. spammers negative-tested it too. it was
ok for them as well :>)
