[Dovecot] Fedora Core 3 and Mail.app problems
Hello, first thanks for all the work, I appreciate the attention to security :-)
I have a performance issue I am trying to solve. On my new server it would appear that synchronizing changes between the client and server is taking longer then my previous setup. I have recently upgraded from my old server to a new home (the basis for my comparison),
From: p-II.
- Redhat 9.0, uw-imap, using self-signed ssl certificates, on an old
- Only one email user (me), about 40 mail folders with a few dozen messages in each.
- Performance was never an issue, Mail.app took maybe 20 seconds to sync up minor deletes etc.
To a new home: format from uw-imap.
- Clean install of Fedora Core 3 on a p4, dovecot-0.99.13-3.FC3.
- Copy of /home/gturner/mail directory to new server, ie existing mbox
- Recreated new self-signed certificates on new server, manually added the self-signed certificates, connected with no problems.
- Mail.app client, on OS X 10.3.9 (no Tiger yet).
I deleted the account on Mail.app, and created it again, the first login/sync took a long time, which was expected.
However after that, I noticed that when I first connect or delete a file the sync is slower then the old setup (FYI, I keep "Automatically synchronize changed mailboxes" checked on Mail.app).
A result of this appears to be some corruption of some mailboxes, only one or two, nothing valuable. For example, I delete a file and then clear the trash while things are still syncing. So my current solution is to be patient. :-)
Any suggestions?
I know that I could covert everything over to maildir, but I would like some feedback to see if this would be reasonable.
I also noticed that initially there are 3 'gturner imap' threads and the syncing seems to be flying along. Then the thread count goes to 5 or 6 and sync starts to crawl. I looked for a way to limit the number of spawned threads, but only saw stuff about 'waiting' threads or reference to 1.0.
I have attached my dovecot.conf for reference.
Any help is greatly appreciated, Gord Turner.

You may or may not be aware that there is a problem with Mail.app in
10.3.9 and IMAP (specifically IMAPS) connections. These problems have
been discussed at length in the OS X 10.3 support forums at http://
discussions.info.apple.com/macosx3mail/. It seems to be an odd bug
though, as it does not affect all users and may be related to the
IMAP server they're using.
I had the problem with Mail.app in 10.3.9, talking to my Dovecot
IMAPS server. I've upgraded to OS X 10.4 and the problem appears to
be resolved. Apple should, however, produce a fix for the bug
introduced in 10.3.9 in a future update.
Hope this helps.

Great thanks very much Rik, I guess I will be fast tracking my upgrade.
Thanks! GT.
