The Courier open source mail package does, and the Coremail service in China. The popular Dovecot and Cyrus IMAP servers do not.

I've talked to some IMAP developers who say that yeah, going to UTF-8 would be great but cleaning up a decade of old character set cruft will be a lot of work. -- Regards, John Levine, johnl@xxxxxxxxx, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
