Anybody Verizon.net mail admins around?
I have a downstream customer on a newly-deployed IP allocation that can't get to pop.verizon.net (connections just time out). I can't either ping or telnet to that either but can connect with s_client. I'm *on* verizon (fios)...
Yeah, apparently they only allow SSL-wrapped connections on 993 and 465, block ping/traceroute, etc. (makes it hard to debug). However, I believe the customer when they say the computer is configured correctly, because it is a notebook and works on another network (both at our downstream, in a different IP block, and a fast-food place with free wifi).
Maybe they only allow secure, at least from some locations. (Just for reference, I'm seeing pop.verizon.net at a 206.46.x.x address, no v6.)
Me too (didn't think if they might have different IPs in different locations). I see pop.verizon.net is 206.46.232.132.
(not saying that they don't filter, but there are no 107 prefixes in the current cymru fullbogon4 list fetched about 5 minutes ago.)
I don't know; that's just a guess on my part that it may be the problem (seems to fit). -- Chris Adams <cma@cmadams.net>
