Look, I understand it's a thin line battling spam and abusive behavior from mail servers. I've pleaded with many blacklist operators to give me details as to why they are blacklisting one of our servers. I can probably count on 1 hand how many times I've gotten information from them in the 20+ years I've been doing this. And I get it. If I'm a spammer and you disclose what is causing the IP to be blacklisted, then I'll change my tactics to get around that method. But you've also got to see it from the other perspective. If I'm not seeing any activity to indicate that the IP is sending out spam... how do you expect me to stop whatever activity is causing you to blacklist the server (I'm assuming you're blocking it because of some type of activity... surely you're not blocking it just because you can)? Maybe other blacklists isn't a good indicator. But if the IP is not listed in Spamhaus, Spamcop, Sorbs, Proofpoint, Symantec (lately I'm having more issues with Symantec, so I'm not sure how reliable it is anymore), and if the IP has a solid Senderscore and a good reputation at Senderbase, and I'm literally just not seeing any malicious activity on the server ... what else am I suppose to check? I'm actually not totally against default deny ... which if AT&T is really not seeing any bad behavior and is just blocking it because they can, they may be doing a default deny. But my issue is, if it's default deny... why on earth does it take a week to clear it? Can you not optimize that to where you confirm-opt-in a postmaster@ email address to clear the default deny... and then you have an email address to send abuse reports! I also don't mean to be picking solely on AT&T at the moment. They're not the only ones that do things like this. They're just the one I'm having issues with right now. I've had similar issues with Hotmail, Yahoo, AOL, Verizon, etc in the past. And like I said, I get it... it's a thin line. But there's got to be some way that these providers and legitimate mail server operators can communicate and determine why a blacklisting is happening so that that activity can be stopped. And if no such activity is happening, then why are you blacklisting it? _______________________________________________ mailop mailing list [email protected] https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
