I've recently encountered an issue with my IMAP folders on Dovecot 2.0.19. When I telnet into my account and perform a list, I get the following response:
A list "*" "*"
* LIST (\Unmarked) "." "INBOX"
A OK List completed.
However I know there are subfolders here and have examined the server directly via SSH and strangely:
a select INBOX.Clients
* OK [CLOSED] Previous mailbox closed.
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.
* 0 EXISTS
* 0 RECENT
* OK [UIDVALIDITY 1394028715] UIDs valid
* OK [UIDNEXT 1] Predicted next UID
* OK [HIGHESTMODSEQ 1] Highest
a OK [READ-WRITE] Select completed.
Just not sure why a LIST is not giving me a full list. This is also affecting connecting to my IMAP via Thunderbird as I can only access my INBOX. Any ideas on how to diagnose the problem?
