Hi Hajo, this looks great! I'm an Emacs addict though, and the main reason I'm not using Gnus anymore is that I haven't found a IMAP syncing solution that "just works" (last time I've checked). Since it sounds like you've solved this problem, is there any chance the syncing module can be run standalone? If so I'll most definitely chip in on your Kickstarter.
Sorry to disappoint you, but i did not find a solution to make IMAP sync correctly. I circumvent the problem by running a gateway that will be continuously connected to the IMAP server. The clients that connect to the gateway, which can do proper syncing :)
So syncing between my mail client and mail clients from other people will be as frickle as ever. What this project aims to do right is offline mode and syncing between multiple instances of my mail client.
I think that used to be my setup, except with mairix. It's a while ago and I don't recall now why I was unhappy with it. But seeing that offlineimap is still actively maintained and has seen plenty of updates in the meantime, maybe I should try again. Thanks for the heads up!
