(MailNews Core :: Networking: IMAP, defect)

I have several public folders on mail server, which work flawlessly in TB2 but since the very first beta of TB3 they are not accessible anymore. The bug is caused by TB sending wrong folder names to server in IMAP queries. Here are server logs:
1 - TB3 connection:
192.168.0.60    [17B0] 12:00:22 <<< 16 select "FAX/FAX"
192.168.0.60    [17B0] 12:00:22 >>> 16 NO SELECT Mailbox does not exist
192.168.0.60    [17B0] 12:00:25 <<< 17 select "INFO/INFO"
192.168.0.60    [17B0] 12:00:25 >>> 17 NO SELECT Mailbox does not exist

2 - TB2 connection:
192.168.0.60    [12C8] 12:04:41 <<< 3 select "FAX"
192.168.0.60    [12C8] 12:04:41 <<< 4 getquotaroot "FAX"
192.168.0.60    [12C8] 12:04:41 >>> 4 OK GETQUOTAROOT Completed
192.168.0.60    [12EC] 12:04:46 <<< 3 select "INFO"
192.168.0.60    [12EC] 12:04:46 <<< 4 getquotaroot "INFO"
192.168.0.60    [12EC] 12:04:46 >>> 4 OK GETQUOTAROOT Completed

TB3 makes this "BLAH/BLAH" doubling of folder name in query, while this folder is just "BLAH". I ckecked for doubling in prefs.js, but public folder configs of both TBs are equal:

user_pref("mail.server.server1.namespace.public", "\"SERVICE/\",\"INFO/\",\"FAX/\"");

there is no doubling there anywhere.

Reproducible: Always

Steps to Reproduce:
1.Have IceWarp Merak server 9.3.1
2.Set up a public folder for an account
3.Try to access it with Thunderbird 3 (any build through 3.1.2)
Actual Results:  
TB3 says that server replied "Mailbox does not exist" s oit cannot access this folder.

Expected Results:  
Should show folder content (defauld behavior)

It could be a client&server related "incompatibility" issue, but anyway there should be a way to fix this without server-side modifications.

Experiencing this with 68.1.2 too with a IceWarp Merak server also.
