For the last 3 days, I have not actually received any new messages. Thunderbird apparently is connecting with the Verizon server and the green bar expands as if the messages are about to appear. Then the process simply stops and no email is added to my inbox. The totals remain unchanged. My last email arrived the morning of 4/2. I have tried closing and reopening Thunderbird to no avail. I have left it running for hours at a time. Don't know how often it checks for messages. And I've clicked on Get Messages numerous times. Messages were appearing in small amounts intermittently in late March; so I guessed it was a timeout message and changed the appropriate setting from 100 to 1000. That seemed to improve things temporarily. But suddenly I stopped receiving new messages. I am not getting any error messages. Thunderbird just doesn't obtain my messages from Verizon. Any help will be appreciated. This is very frustrating.
