I really really liked squirrelmail when my host used it. It wasn't perfect but had lots of plugins and was light and fast, and was open source. It was ugly though, and had a few bugs. Then my host pushed, despite objections from the community, atmail, a proprietary gmail-alike webmail interface. It is even more buggy, and slow as hell, but hey, at least it looks "cool".
