Favorite Free Webmail Interface?

[justhost]

I am curious what peoples favorite FREE webmail program is?

I had always been partial to SquirrelMail, however, it has been having troubles displaying accounts that have a couple thousand messages in them so I have been looking at horde more closely.

I would be very interested in seeing what other people think.

gmail is really nice. I only use it for mailing lists and it handles them great.
