Hi, I too, am using muchsync to synchronize between two machine, I too have profited from David's quick responses, and I too deal with the problem of only being able to "fetch mail" on one machine. I followed the discussion with interest. Looking at the isync (mbsync) docs (I can't speak for offlineimap) it might be easier: the state of the sync seems to be kept in little files per Maildir subdirectory, called .mbsyncstate and .uivalidity. If muchsync were to sync these files as well, then I think it would work. See the explanation of the .mbsyncstate file in this thread: https://sourceforge.net/p/isync/mailman/message/34682807/ quote: "mbsync maintains a mapping of remote (col 1) to local (col 2) uids. when you migrate, you can just duplicate the columns." He's talking about migrating a mail store from offlineimap to mbsync, I guess the issues would be the same.
