I've recently tried to find a good free mailservice supporting iMap, but so far I've no good luck.. 
YAHOO - removed their IMAP support a year ago, so no go there anymore.
AOL/AIM - U.S. only. Has iMap support but no option to select another country when signing up, so I guess they don't really want foreigners to sign up either. (They're almost only marketed in the U.S. so I can understand why.)
GMAIL - I use this now, but there's no iMap, which makes me sad..
.MAC - has iMap, but is not free.
(I'd wish they'd atleast provide a 100MB free .mac mail adress to all Mac users, but if they did it would only be POP anyways..)
Then there's stuff like Bluebottle, Crazymail and so on, but I don't know how reliable they are, so I thought maybe you knew about some good services?
