With normal greylisting it resolves itself within an hour of the first 
email with the source-destination-SNMPserver tripplet.

Graylisting is a hack, but it is a well-working hack which together with 
SPAM filtering provides a fairly good damping of SPAM traffic.

If you do not tweak your graylisting to stupidity and do sane management 
of your spam-filtering, you should not have a problem. If you do more 
agressive measures, then it may blow up on you.
