I never linked my Verizon and Yahoo accounts. (always thought was a bad idea.) Instead, I setup Yahoo webmail to retrieve Verizon mail so I could check it same time as Yahoo mail while at work. This allowed me to also download via Thunderbird on my home pc. Never had problem until, a few days ago. Suddenly I cannot get any Verizon mail on yahoo webmail page. I've tried every variation of old and new port numbers and settings with no luck. I can still receive other non-yahoo pop3 mail there but not Verizon. Any ideas?
