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).

Me too (didn't think if they might have different IPs in different
locations).  I see pop.verizon.net is 206.46.232.132.

I don't know; that's just a guess on my part that it may be the problem
(seems to fit).
