Job, I already taught my SpamAssasin and then deleted them, and my Postfix is no longer taking submission from the IP from which they were sent - 216.176.196.72.
They seem to be using correct sending host according to SPF record (host spamtitan.csvwebsupport.com validates using '[email protected]’). Let me unblock them again and see if they’ll continue doing so, hopefully I’ll be able to help. I’m sending this email just to (hopefully) trigger the same behavior, and will follow up with you separately. Apologies for the noise for the rest of subscribers. -- Łukasz Bromirski CCIE R&S/SP #15929, CCDE #2012::17, PGP Key ID: 0xFD077F6A
