I had this same problem, clone and built from source and the problem went away.

Thanks for this great software and having clear instructions on the README for a clean build.

+1, built using origin/1.4 and I am no longer seeing this issue.

Any chance for 1.4.1 release? With multiple new messages in multiple folders (mailing lists, build logs etc) it takes isync quite a while to synchronize fully when invoked with interval of 10min.

Thank you! I can confirm that 1.4.1 works in my case!

For me this is 100% reproducible with FastMail server:
1. Ensure new email is received not tracked by isync
2. Invoke mbsync to fetch new message
3. Open mail client to read it
4. Invoke mbsync again to mark mail as read on remote side

Last step always results in "unexpected FETCH response". Next invocation always succeeds.

that guess is certainly correct, though usually that would happen only if you did one of these things on the server and the other on the client. but you have server-side overlap between All Mail and the other mailboxes, which mbsync doesn't know, so it thinks someone else is doing the things it's actually doing itself. that's in fact quite possibly the trigger for the real problem, even if it really shouldn't.
