I have been impressed with the features of muchsync when I recently found out about it. muchsync seems to do everything i want: i have my server where i usually take my mail, but then my laptop that i want to sync and run notmuch + emacs on...
however, when i tried it, it failed: [1011]anarcat@angela:~$ muchsync -v --noup --init Maildir marcos.anarc.at [SERVER] [notmuch] Note: Ignoring non-mail file: /home/anarcat/Maildir//.Archives/dovecot-uidlist [SERVER] [notmuch] Note: Ignoring non-mail file: /home/anarcat/Maildir//.Archives/dovecot.index.log [SERVER] [notmuch] Note: Ignoring non-mail file: /home/anarcat/Maildir//.Drafts/dovecot-uidlist [...] [SERVER] [notmuch] Note: Ignoring non-mail file: /home/anarcat/Maildir//courierimaphieracl/notmuch [SERVER] [notmuch] Note: Ignoring non-mail file: /home/anarcat/Maildir//courierimapkeywords/:list [SERVER] [notmuch] Processed 53 total files in almost no time.

I don't think it dumped core - if so, I couldn't find the core file. Note that only 500MB of mails were transfered, out of around 11GB of notmuch db + mail in my remote maildir. Anyone using muchsync with similar data sizes? I'd love to get this working - I had trouble reseting my offlineimap + local notmuch synchronisation the last time I tried... Notmuch tags would not get assigned properly, for some reason...
