Steps to reproduce:

Trying move local folder (by drag-and-drop) which contain hierarchy delimiter in their name to IMAP server result in serious errors, which, in addition, are not reported to users. In my case I had TB 24.3.0/WinXP-i386 client against dovecot-2.2.10 IMAP server (it has dot (".")  as hiearchy delimiter). As test case here I tried move two local folders with names "sak." and "tak..", each containing one short mail message. These local folders I tried move to IMAP folder INBOX. For comparison, I also moved one folder with good name "rak".


Actual results:

1a) Attempt to move the "sak." folder ended up creating a folder "sak" (which was visible only after restarting TB or after some fiddling with Subscribe manager), and message which was under "sak." was not copied.
1b) TB report no error, but
1c) into destination folder (INBOX) then was not possible move anything - even folder with good name or message alone.

2a) Attempt to move the "tak.." folder ended up optically as nothing happen,
2b) TB report no error, no subfolder was created in destination IMAP folder, and
2c) into destination folder (INBOX) then was not possible move anything - as under 1x).

Attached are PCAP files with client-server (TB<->dovecot) communication, as sniffed with tcpdump, and also their appropriate ascii dump files created by wireshark. For comparison there are as well similar files when move good-name folder (with one email inside).




Expected results:

IMAP operations on messages and folders should be reliable, eventual errors should be reported (otherwise there is a risk that the user after copy/move delete the source folder, because he would think that it was copied/moved successfuly)
IMO the reality today is such that e.g. last MS Outlook has more reliable and more powerful IMAP messages and folders handling than TB - although it was reversely for years. (Of course, Mozilla users can be amused every month from another, more and more impractical UI ('Preference' menus are absolute **** IMO ;)
