Yeah it's REALLY bad. Funny thing is, and I don't know if this is store-specific or what but as an Apple employee working at the retail store, I got access to all of my email thru squirrelmail. You could only hit it from behind their firewall, but it's http://webmail.apple.com (it will fwd to https://webmail.apple.com/src/login.php if you cancel out of the login prompt, which for anyone who's used squirrelmail, is the standard login page)

Of course I was also given a mobileme account (which uses a pretty slick desktop-like web UI for mail) but I was shocked that they didn't do like a Google-Apps style rebrand of MobileMe email for their own @apple.com accounts. Pretty sad if you ask me.

Already mentioned by sucuri2 in another thread, but roundcube (http://roundcube.net/) looks much more attractive. Still not GMail, but much nicer than squirrelmail.

If you pull down devel-threads from svn, add a couple of plugins, and tweak a few things, RoundCube IMO actually gets better than Gmail.

Interesting. I've liked Roundcube enough to use as a backup way to access mail, but I've never looked at the plugins.

What are some of the plugins that you find useful?

The spamassassin plugin lets you control your spam settings from your webmail account.

I also have managesieve installed, and there's a plugin for it too, so with imap, inbound email gets automatically sorted into folders for me, and I can control that from RoundCube. The filtering is actually way more powerful than anything Gmail can do (last time I checked).

Those are the two "must-haves" IMO.

I agree, it used to use frames, which was rather annoying. But if you don't need too many features, it works.
