I have Postfix reject_unverified_sender for the "free mail" domains (e.g. hotmail) and for some highly spammed recipients. If a spammer sends a message with the from set to one of your traps, my Postfix will test to see if the sender exists [e.g. a failed test
Mar 13 05:23:53 srv postfix/smtp: 8B1734F00A5: to=<firstname.lastname@example.org>, relay=none, delay=0.07, delays=0.01/0.04/0.02/0, dsn=4.4.1, status=undeliverable (connect to mail2.ofloan.com[184.108.40.206]: Connection refused)]
If this sender was a trap of P.H.P., would my server now be labeled a spammer?
