Thanks a lot, Leena. :) You've actually tickled some suspicions we have
also had, that to deliver good Webmail service to our users, we may have
to figure out PHP acceleration.

I sometimes wish the world wasn't so desperately pushing the one-size-
fits-all paradigm of browser-based apps for each and every thing in
sight... all this problem with Webmail is primarily due to using a
connectionless run-time system for a connection-oriented service (IMAP).

Will look into PHP cacheing and other stuff.
