The orignal question...
I'm running Dovecot0.99.13 on Fedora Core 3 and things work fine when using either Thunderbird 1.0 or Outlook Express as IMAP clients. Outlook (2002 SP3) on the other hand runs incredibly slowly, or just outright hangs.
I've discovered that if I delete and recrete .../Maildir in the user account such that the directory exists but is empty, then outlook seems to behave. If on the other-hand, I try to create a folder, with outlook, outlook will hang and the folder won't be created. If I create the folder with another client and then go back to using outlook, outlook will hang.
I've taken some network traces and have annotated them here... ..
The problem with these traces is that they're not complete.
Now try to create a sub-folder using outlook: 0.000000 192.168.73.1 192.168.73.3 IMAP Request: DONE 0.000587 192.168.73.3 192.168.73.1 IMAP Response: 0006 OK Idle completed. 0.000910 192.168.73.1 192.168.73.3 IMAP Request: 0008 IDLE 0.001113 192.168.73.3 192.168.73.1 IMAP Response: + idling
For example in here the CREATE command is missing completely. This is most likely because only the first line of each IP packet is shown.
Also is it Dovecot or Outlook that hangs? You could try straceing the Dovecot's imap process while it's running to see if it's waiting in poll() or doing something else.
I don't think I've heard of similar problem before though, so probably somehow specific to your installation..
