In theory I have about 70^63 - 10 spamtrap addresses, 10 local
parts incl. nobody@ I actually use (with a PASS). Anything
else is bogus, gets a FAIL, and for some time I was able to
report all mails (spam + bounces) sent to this ersatz-spamtrap.
Real spamtraps are of course supposed to handle anything they
get immediately, no POP3 V90 whatever delays, and something in
the direction of "op=auth" if some addresses are still used to
send legit mail. To avoid any confusion like typos in replies
it's probably best to reserve a complete domain, or use an old
domain without this "typo in local part of legit reply" issue.
