It took me nearly an hour to find out through a Verizon tech support chat that pop servers are blocked for international access! This means on web access will work, you can't use your e-mail client to access Verizon e-mail when travelling abroad. Verizon - please post this policy on your support page to save people time having to learn the truth!
For people like me who travel abroad a few times a year and have multiple e-mail services, this makes a compelling case to use a different e-mail service like gmail that has no problem with this. Also, I find the user interface for Verizon web access to be inferior to most common e-mail clients like Outlook, Windows Live Mail, etc.
