I've got some issues with dovecot, that I need to resolve, I only have about 20 users in the office, but the average disk space used by each user is anywhere from 1GB up to at the extreme end of the scale 7GB. I'm using the mailbox format. The server is a P4 2.8 with a 1GB of ram and run off 250GB SATA disks. most users have lots of structured folders going as deep as 6 levels. The problems I'm getting are odd the problems that I'm getting at the moment are "cannot copy mail to sent folder", but sends the message fine, this doesn't happen all the time but happens to everyone but me... I'm using OS X's Mail.app which seems to always work:) all my users are using W2K and either ThunderBird or Mozilla The other problem which I've been made aware of... The users get the "loading message" or "opening messages" and the egg timer goes round but never completes. I managed to clear the problem by getting the user to close their email client and then kill their IMAP processes on the server, when the user logs in again the client responds correctly. Is there something I'm doing wrong with the configuration of dovecot? would using MailDir help, I dont want to migrate from Mailbox unless this change will make things better, I understand their are benefits from using MailDir, but I dont know if I will continue to see the same problems if I migrate. Any help or advise would be great, I should add that everyone is connecting to the server over SSL Gabe

Maildir probably won't help anyway with these problems.> Any help or advise would be great, I should add that everyone is > connecting to the server over SSLBut you didn't say what Dovecot version you were using.

Hi Timo, Thanks for your reply, Closing the email client doesn't kill the process, it does sometimes but normally have to wait a while (5mins or more). When you refer to CPU load are you talking about on the server itself? if so I don't believe it is. I will check next time this happens. My largest users mailbox file is 200Mb with the total disk space used by all their mail folders is 6GB. Is there any information regarding limits on what is a safe maximum size for a mailbox folder? I try to get my users to keep their inboxes under 200 messages or 50Mb. Currently I'm gettting my heavy users to reduce their inboxes from 150Mb down to something sensible. As for the the version of Dovecot I'm running its 1.0-stable on linux(SuSE 9.1, tho I wish it was a debian box) a 1U Intel P4 2.4 1GB DDR 2 * SATA 250 Drives running RAID 1.
