at noon we switch to mail_cache_fields = after that the the clients are usable again.
test5 should be even more usable with this.
BUT what we can do? what would be the best choise for us? the parameters: ..
- we've got about 300 mailbox
- most people just has mails in his inbox and sent folder
- this folder are real huge (a few thousend mails)
- 300 mailbox has 100000 mails which is about 16GB this means the avarage message size is about 160K (actualy the size are 5-10K or 1-5M)
so what extra (non default) parameters should I have to use (eg: mail_cache_fields etc.)
There's not really other settings that affect it. I've tried to make Dovecot handle large mailboxes fast by default, but I haven't really thought of the rebuild slowdown before.
Well, yes, to be safe. But usually you shouldn't need to delete the .imap* files at all. If there's any changes in format or whatever, it's rebuilt automatically. It's needed only if it contains actually invalid data that can't be detected, like there cached ENVELOPE texts were wrong before.
they were wrong in any previous version? or how can I know that?
NEWS file contains everything that's needed to know when upgrading, including if index files should be deleted because of old bugs. Except I forgot to update it for 0.99.8.1 which fixed one of these.
