rsync and "mail retrieval agents" (this actually isn't the right term
either) are TOTALLY different animals. The difference lies in the fact
that software agents such as imapd and pop3d are designed to be part of
a mail processing chain. The input to these agents is a mail storage
structure, mbox, maildir, maildir++ or whatever. The output is designed
to conform to a RFC-standardized communications protocol (IMAP, POP3).
These protocols deal with _messages_ and are independent of the details
of the mail storage structure. rsync, on the other hand, is a file
management utility which should make faithful reproductions of file
system structures. It doesn't know a maildir from a website or a python
library.
