I have a very bizarre problem that I hope someone can help me with. I am not sure if this is a Dovecot problem, or IMAP client problem.
I recently used Transend's Migrator to move mail from Exchange 2007 to my Dovecot 1.0.7 server. The program seems to have moved the nested IMAP dirs properly as seen below in a directory listing of the maildir dir. The nested dirs have indexes, cur, new dirs as expected.
However, when the account is viewed in Windows Thunderbird 3.1.6 or Outlook 2010 the 3rd tier dirs are not seen, nor can they be subscribed to. On a whim, I decided to try Apple Mail 4.3 to view the account and all the IMAP dirs can be seen and accessed as expected.
Any idea what is going on? Is this somehow an IMAP client problem (bug) or an issue with Dovecot and these clients?
Listing of the Maildir dir:
[root Maildir]# ls -al total 92 drwx------ 17 andrew andrew 4096 Dec 6 17:06 . drwx------ 9 andrew andrew 4096 Dec 6 15:58 .. drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox.mail drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues drwx------ 5 andrew andrew 4096 Dec 6 17:02 .mailbox.mail.colleagues.amy drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues.aslan drwx------ 2 andrew andrew 4096 Dec 6 16:31 cur -rw------- 1 andrew andrew 144 Dec 6 16:31 dovecot.index -rw------- 1 andrew andrew 10272 Dec 6 16:31 dovecot.index.cache -rw------- 1 andrew andrew 128 Dec 6 16:31 dovecot.index.log drwx------ 2 andrew andrew 4096 Dec 6 16:31 new drwx------ 5 andrew andrew 4096 Dec 6 16:53 .Sent Items -rw------- 1 andrew andrew 32 Dec 6 17:06 subscriptions drwx------ 2 andrew andrew 4096 Dec 6 16:31 tmp drwx------ 5 andrew andrew 4096 Dec 6 16:32 .Trash
PROBLEM:
When viewed in Thunderbird 3.1.6 or Outlook 2010:
These nested dirs are seen: ..mailbox ....mail
These nested dirs are NOT seen or can be subscribed: ......colleagues ........amy ........aslan
OBSERVATIONS:
When viewed in Apple Mail 4.3, all dirs are seen correctly.
Thank you, I appreciate any and all replies, comments, questions, and suggestions. Jason
