Well, Netaxs is lying, either through ignorance or intentionally. They are indeed using a realtime blackhole list, www.uceprtotect.net, and blocking mail from Verizon mail servers. The UCEprotect methodology is here: http://www.uceprotect.net/en/index.php?m=3&s=0
Level 1, which your Verizon servers are listed under, is here: http://www.uceprotect.net/en/index.php?m=3&s=3 To be fair though, "they" aren't seeing it, but their mail servers are, which query the RBL/SLS database. But this is the problem with ISP filtering: they don't give you any mechanism for false positives, which remain a problem with spam filtering. No matter how good your system is, you will always have FPs. I've said it before: email is no longer a reliable form of communication. It's broken; don't depend on it. > -----Original Message----- > Here is something interesting that has been happening with good ol' > Netaxs, now a part of PAETEC. > > Frequently I stop getting any kind of mail at this addie for, say 12 > hours.
