 ## Mail attachments

 # this for now.

 # Filesystem backend to use for saving attachments:
 #  posix : No SiS done by Dovecot (but this might help FS's own deduplication)
 #  sis posix : SiS with immediate byte-by-byte comparison during saving
 #  sis-queue posix : SiS with delayed comparison and deduplication
