Tips

Automatically sync all folders in Thunderbird

From here:

• open the Config Editor (Tools → Options → Advanced → General → Config Editor),
• change the mail.server.default.check_all_folders_for_new setting to true.

Troubleshoot

Sent folder not updated

Like a corruption of the TB database [1]. Go to ~/.thunderbird/*.default:

sqlite3 global-messages-db.sqlite vacuum

Mail not deleted

Deleting a mail seems a hard task in Thunderbird [2]:

• Set mail.imap.expunge_after_delete to true.

Missing mails, IMAP folder not synced

• Right click on IMAP folder, select Properties.
• In the General Information tab, click Repair Folder button.

Sync bugs

• bug 712595

About IDLE, and CONDSTORE flag/support.

Proxy not working

• Proxy does not work with IMAP. See bug 1263295 and bug 1230823.

• Refuse to connect to localhost in all possible ways.
• Only work-around is to keep the proxy disabled, and enabled it only when e.g. to sync Owncloud address book.

Broken text edition mode

• Relevant bugs bugzilla 216132, bugzilla 140800
• Relevant posts mozillazine
• My bug bug 1288914

Fix:

• In Preferences → Composition → General → HTML Font, select Variable Width. This way this makes apparent that edition is in HTML mode. Also, there will not be a weird font change when pasting text at the end of a reply.
• To force text-edition mode, use Shift-click on either Write, reply or forward.
