In some cases users have a symbolic link like "z: -> /" in their mail directory. As a result there are log entries like
stat(/home/xyz/.wine/dosdevices/c:/windows/profiles/xyz/.../z:/proc/28381/root/proc/28381/.../root/proc/28381/Player/#SharedObje Jan 25 13:30:31 imap1 dovecot: [ID 107833 mail.error] IMAP(xyz): x) failed: File name too long
Like you, our users store mail in their home directories* and sometimes they make symlinks to strange places like -> /usr.
I patched dovecot to simply ignore symlinks; maybe you can, too.

- although we're finally starting to convert our 30k users over to dedicated maildirs+NFS. I'll share my experiences with the list once we're done (early March I hope).
