I used to sync my two server's maildirs for some years, but I moved to
dsync mirroring some months ago, and now I'm into using replicator/dsync
(see archive of March 2012).

Unsion mirroring is working in general, but sometimes you might realize
some duplicates being produced. Not bad, but it happens. I did realize
the same with using dsync mirror instead. It's much better with the new
replicator/dsync mirroring scheme, but it's not perfect, yet. (Again, see
ML archives of the last weeks).

I used ...

	ignore = Name dovecot*
	ignore = Regex .*/tmp$
	ignore = Regex .*/\.Drafts$

… to ignore all of them. When runnig mirroring for the very first time, I
started with one empty maildir at one server, IIRC. You better check that
with a test maildir beforehand.

That became mirrored.
