"(" and ")" fails, this was tested by Till. "@" fails with virtdomain
enabled. "'" also fails, this was reported by 4 different people. "&" is
used as part of the RFC3501 encoding and I cannot remember if they had an
special escape for it.

So what would you propose as a solution to this.

I blame maildir because I have no problems with folder names on non-maildir
IMAP4 server. It might just be Cyrus issue and not a file system issue. 

/me no longer will I blame files systems :)
