North American Network Operators Group Date Prev | Date Next | Date Index | Thread Index | Author Index | Historical VerizonWireless.com Mail Blacklists
It appears VerizonWireless.com has some rather aggressive mail filters. Verizon.net's blocking of Europe, Asia, Africa... well, everything but North America has made some headlines and even some lawsuits. Anyone know if VerizonWireless.com and Verizon.net are independent operations from an SMTP point of view? Verizon.net has, http://verizon.net/whitelist And I haven't found an equivalent for VerizonWireless.com. And given the differences in Verizon.net's and VerizonWireless.com's MX setup, I doubt they use common resources. Anyone here ever get off of their blacklist or even know what they are using? Even though we have accounts with them, I haven't been successful in getting through to clueful help *shock*. FWIW, it really looks like an IP-based blacklist. From our main mail server to any of their MX hosts, the 25/tcp connection completes, but then their server drops the connection, no banner, no nothing. I get a banner and can send mail to their servers from other IP addresses outside of that network. My guess is that they're using SPEWS? We're collateral damage in a SPEWS block. -- Crist J.
