As you may or may not have noticed, webmail (imp anyway) is broken due to a bug in the php4-imap package. Due to this I've moved the current webmail links off the main page (out of temptation) and put up Squirrelmail, another decent webmail implementation. The link to the right points to this right now, please use it to access your mail until I can get the other webmail fixed up.
Update: *sigh* looks like squirrelmail is b0rked as well. I'll get it all going one of these days. Lets try another one!
