I googled for rsync and maildir, and found this:
http://www.nabble.com/Rsync-snapshots,-Maildir,-and-Sarbanes-Oxley-td11914169s24859.html
It mentions using the --fuzzy flag. From the rsync man page:
-y, --fuzzy
This option tells rsync that it should look for a basis file for
any destination file that is missing. The current algorithm
looks in the same directory as the destination file for either a
file that has an identical size and modified-time, or a simi‐
larly-named file. If found, rsync uses the fuzzy basis file to
try to speed up the transfer.
Note that the use of the --delete option might get rid of any
potential fuzzy-match files, so either use --delete-after or
specify some filename exclusions if you need to prevent this.
(and a note to myself on the last bit: I'm currently using --archive
--delete, so that's something to look out for. I guess that my new
arguments will be --archive --fuzzy --delete-after)
