You might have marked a message 'read' on one machine and if the two get out of sync on another machine, you might have the same message unread there. > > How about using pseudo-mails stored in Maildir and synchronised by > > IMAP?

I've had formail+procmail delete my duplicates for 10+ years, and while I don't like the fact that I usually get the CC before the list mail, and thus cannot filter on Delivered-To, I have never looked back. > Second, the only reason I would be interested in synchronizing mail > between two systems is so that I could manipulate the tag data in > multiple places, (that is, remove the "unread" tag whether on my > network-disconnected laptop or via web-mail when away from my > laptop).

IMAP does not really allow for conflict resolution, which may well be *the* reason why you cannot update existing messages. > [*] Though, I think a plain-text file with tags managed with > something like git (and perhaps a custom merger) could save a lot > of work.

Git is good at conflict resolution if run interactively, but  still makes me question whether it can ever take the place of IMAP. However, Asheesh Laroia, who has floated the idea of Git-for-mail at DebConf8 already, has some ideas and hopefully will soon reply to my mail , which I just bounced. 0. http://notmuchmail.org/pipermail/notmuch/2010/001114.html -- martin | http://madduck.net/ | http://two.sentenc.es/ apt-get source --compile gentoo spamtraps: madduck.bogus at madduck.net -------------- next part -------------- A non-text attachment was scrubbed...
