i ll do backups with rsync on maildirs with courier
( which has also : in filenames )
without any problems, as well i backup whole machines
including sockets etc without any problems
so the problem cant be dovecot here
check your rsync version and script i would guess, maybe cifs has
problems ..., use ssh ,ftp, nfs etc instead, or backup rsync in a local
dir first then tar it followed by copy over cifs just one tar file
