I have multiple email addresses managed by Thunderbird. Recently one of my address stopped receiving email, other addresses work fine. I am able to send email from this address but can not receive.

Status line at bottom of window quickly flashes that it's contacting my server, then indicates "Connected to ...." my server. This messages remains for about a minute then disappears. Last email received was about 2 weeks ago. I've had to login directly to my server which is a total pain.

SDJ1,
