We set up the perfect server following http://www.howtoforge.com/perfect-se...64-ispconfig-3
with the change that we used roundcube rather than squirrel mail. This was done over a year ago and since then we have always suffered with roundcube being really slow when a user has more than 1000 emails in their inbox.
This is now becoming a big issue as more users are going for webmail. I have read that it may be due to server side sorting through courier although I don't know how to change the courier config to disable this (not even sure where it is, I'm new to this part).
Any advice would be appreciated. Also these servers are live so I'm looking for a fix, nothing too radical. I'm running .7 for roundcube and not sure on the courier version (where can I find it?)
Thanks in advance
