about IMAP's "cost", here�s a comment today from the postfix list about " webmail setup": " We recently set up Squirrelmail here, and people really like it. However, if you're going to scale to the 10K user range instead of 1K, and if you're concerned with keeping resource usage low - a good concern - I would recommend you look for non IMAP-based packages like the Courier webmail or the sqwebmail mentioned above. Squirrelmail (and the other IMAP-based packages we looked at) sets up and tears down an IMAP connection for each web page load, and may even do multiple IMAP connections - not transactions - for some pages. This is a worst-case scenario for the IMAP daemon and if some of your users have large mailboxes you may end up badly I/O bound. (I/O proportional to mailbox size * # of mouse clicks.) It's going to take a lot of code to change this behavior, so better to go with a package that doesn't have that problem in the first place.
