[Dovecot] Large IMAP operations tend to timeout and cause problems?

[Alen Salamun]

Hello all!

I have moved from Courier-IMAP to Dovecot some month ago. It is quite 
stable on everyday use (1.0alpha4) but it has constant problems with 
large IMAP/SSL operations. We use Maildir format.

For example if I select 400 messages, mark them deleted and use "purge 
command" in Thunderbird (to actually delete them) TB starts to do 
something and runs and runs and runs....Then I get script timed out 
errror and I have to restart TB. That never happened with Courier-Imap.
Same thing happens for example moving 1000msgs to another folder or 
something like that.

Another thing is still that from time to time dovecot indexes get 
corrupted and users can't access some folders. Then I have to delete 
dovecot* in that Maildir folder and it works again.

Any thoughts on that please?

BR,
Alen
