Gmail seems to be the best of the bunch by far, offering IMAP and an excellent webmail interface, free of charge. (Yahoo won’t give you IMAP access, and Hotmail … enough said!) I’m using Apple Mail on the Mac, and setup was easy, thanks to some helpful instructions on Geekology (I didn’t use the “IMAP Path Prefix” bit though). A few very minor issues (such as the way many messages appear twice or several times when you seach in “All Mailboxes”), but I’m very happy so far. Except that I still have 191 messages waiting to be dealt with, plus however many are sitting in a queue (I hope!) at Sussex…
