Thanks all, for your support. I did fed spammy emails, most are blocked but users still get bunch of those emails a day. I added this in MTA:smtpd_sender_restrictions = reject_unknown_sender_domain in the .cf file I addes blacklist_from *.review blacklist_from *.work blacklist_from *.dateI would use the following: blacklist_uri_host review blacklist_uri_host work blacklist_uri_host date
you want both: a bad sender using the domain as well a URI to the domain and without having tested it at my own: make sure it does only match when the domain ends with "review", "work", "date" to prevent FP
P.S.: i wonder why people still can reply with the original thread subject - no way that a response with that domain would pass our submission server because URIBL
