Bug Description

Binary package hint: thunderbird

The dialog "Failed to connect to server xy" appears although there is a working network connection.

Steps to reproduce:
1. Close Thunderbird
2. Disconnect your network connection (in my case it is wireless)
3. Open Thunderbird
4. Expected dialogs "Failed to connect to server xy" - since there is no network connection.
5. Click all the dialogs away with ok.
6. Connect your network.
7. Open your favorite website in e.g. Firefox - just to make sure the network connection works.
8. Click "Get Mail" in Thunderbird.
9. UNEXPECTED dialog "Failed to connect to server xy" appears!
10. Click it away.
11. Clicking "Get Mail" again now just works fine.

All the accounts are configured with IMAP via SSL. Gmail and other providers.

It doesn't help to disable the "offline status detection via NetworkManager" in the config editor (toolkit.networkmanager.disable).

This happens under additional circumstances. In my case, a wired connection, and after Suspend, but also with all (two) accounts IMAP and SSL. My variant steps to reproduce:

1. Run Thunderbird.
2. Verify that "Get Mail" works normally in Thunderbird.
3. Suspend the computer.
4. Awaken the computer.
5. Wait for network to re-establish itself.
6. Click "Get Mail" in Thunderbird.
7. UNEXPECTED dialog "Failed to connect to server xy" appears!
8. Click it away.
9. Clicking "Get Mail" again now just works fine.

I can confirm that the problem also occurs after a suspend as Human describes.
