You'd be surprised at the blank stares I've gotten in certain venues when I 
bring up Bounce Processing.

Unpleasantly surprised.



And yes, the time an address remains dormant until it gets used as a trap can 
be a concern; but if it is repurposed, that’s hardly what I would consider, 
“pristine”.

An argument is being made for waiting at least a year, as opposed to the 
previous Conventional Wisdom of 6 months, and … I can see the merit in the 
former.

Aloha,
Michael.

Well, the sender wouldn't know if it's a trap or if the server is just FUBARed 
in some odd way.

Yes, but we're using mailman, and always with double-opt in and (of

course) bounce processing (seriously, who wouldn't use bounce processing?!).



In fact, these spamtraps must have been hit quite recently when we already had 
the most recent version of mm2 (the one with reCaptcha). It's totally unclear. 
To me it looks as if a domain wen'T directly from "used for mail" to "used as a 
spamtrap".
