maildir(5) states that readers should not attempt to parse the filename of a
a message other than the :info field. However, since
.B isync
relies on using the message UIDs that info must be inserted into the
filename in a way which will be interoperable with existing readers. So
the UID is placed in the filename of the messages in the local maildir
mailbox rather than the :info field.
