Hi,

I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing.

I've tried mutt, evolution, kmail, and am now using Thunderbird, and am working on getting Mail.app to import an archive of my 4 Gigs of mail, thinking if nothing else works, I can have a copy of that on the clients I use, though I like having it on the server better.

Can anyone suggest something to fix my problems, besides deleting all my email?

Thanks,

Rob
