It's sad, I'd really like if it were as simple as a naïve rsync. But at
least now I know it's not something weird in my config.

Can you give me some more hints of what would that setup look like? 

I suppose it requires running an IMAP server (dovecot) on each machine I
want to use, and running offlineimap to sync both IMAP servers
(equivalent to rsync in the "plain sync" idea).

I'm currently using Gnus to fetch e-mails. As offlineimap was designed
exactly to sync newly created files, I suppose it will work - I just
need to change the mail folders from nnmaildir to dovecot and save the
new messages there.

What about performance? I suppose it's pretty okay, as the IMAP server
is running locally; and I expect offlineimap to take some more time.


Many thanks for your reply - it is pointing me towards a *working*
solution, and that's what I was looking for :-)
