I’ve been using Gmail more and more for various reasons. Most significantly, Gmail offers IMAP for free, which allows me to check my mail in Thunderbird. Generally, I’ve preferred Yahoo as a free e-mail service. One of the things about Gmail that bugged me is the lack of support for folders (at least in the traditional sense, not labels). I found a cool GreaseMonkey script that uses some JavaScript trickery to convert labels to a folder-like treeview in Gmail. It only works in Firefox with GreaseMonkey installed, but it works pretty well.

Maybe now I finally have a good reason to move away from 1and1′s e-mail service. My only head-scratcher is that some of my mail being sent through Gmail’s SMTP is being marked as SPAM. I’ll have to look into that further – it may be because I’m using a different “reply-to” address through Gmail’s SMTP, which some SPAM filters may flag.
