I don't know what you are talking about. Perhaps you are running mbox which is you problem right there! I have been running squirelmail with Courier-IMAP as the IMAP server and Qmail and the MTA. SM is the easiest to configure and the most standards compliant webmail client which is precisly why I use it. Some of my subfolders have in excess of 30K messages a piece and my Maildir is about 1.2G in size now, steadily growing of course:) My mail server is a K6-233 w/80MB of RAM and I have never had squirrelmail bomb on me. It does run a little slow because of the HW limitations but it has never crashed. I have been using is exclusively for me e-mail now for just under a year. Perhaps your IMAP server is the one that's having troubles. IMP is more fully featured but it also a pain to install/upgrade/maintain too and its not totally standards based.
