When moving or creating an email on the local side, after each sync that email will start to get duplicated.

you clearly have a broken imap server that incorrectly responds to the query

tag uid fetch * (uid)



for comparison, issue

tag uid fetch *:* (uid)

which is what isync did previously (but it's nonsense to do that).

it should return the uid of the last message in the box, but returns nothing.

Thanks, I'll try that ASAP and get in touch with my email provider.

I'll get in touch with their support and link them to this thread.

Thanks for your help, Oswald.

I've tried this and I can confirm that the server simply replies with "OK FETCH Completed" but doesn't return anything in the first case and lists all UIDs in the second. See below.
