Thanx for the response guys. On a side note I actually work for the same ISP as Jon Duggan who has been discussing other issues we've had mainly related to 579.
The performance overall is fine we get no queues, pop3 is fine and general imap is fine. The only issues we have had is related to combined webmail + imap. As said above, imap on its own runs perfectly. With imap and webmail together we've had numerous issues with performance and bug 579. Though, we've been working franticly on things that could help it. I've made the changes that you had stated with regards to innodb in mysql and that seems to have assisted performance slightly. One other thing that we've been testing is with round cube instead of squirrelmail and round cube in my opinion so far seems by far a lot quicker and more reliable. As you may already know this is a live server with between 4-5k of users, i.e. if something breaks we get a phone call pretty much immediately which is nice! lol. Any other suggestions anyone may have with regards to webmail+imap and performance i'm all ears.
