Thunderbird 17.0.2 can not fetch imap because it mixes username and mailaddress.
Let username be firstname.lastname@example.org or 1234 (both can be used at same time)
mydomain.bar runs the IMAP server and email@example.com is an alias to
1. Create a new account with the wizard for a large provider that uses usernames and mailaddresses as USER like domainfactory (http://df.eu)
2. IMAP WORKS
3. Now change the mailaddress and the account name to firstname.lastname@example.org
leave the username in the serversettings as they are. But leave IMAP-SERVER
and USERNAME untouched.
4. IMAP FAILS
Thunderbird is confused and tries to fetch calims it could not fetch mail from
5. The workaround: If you change username email@example.com to the username 1234
thunderbird will fetch from the correct server again and IMAP WORKS.
Upstream? This is a well known annoyance, I think.
should we close
I think Thunderbird 17 is quite old (31.4.0 currently) and no one will
ever care about this bug again.
