Hey everyone, back on the list after a few years away.

I have a strange issue that is just annoying. Trying to work out if it's Dovecot or Thunderbird causing the problem. Basically, I read an email (so it gets marked as read) and then very quickly I mark is as unread, (i.e. I realised I want to leave that email for later) which causes a duplicate email to be created. Generally I believe both duplicates are then marked as unread, but I've not taken too much notice of that part yet, other than the new email (the duplicate) being marked as unread. This has also happened when deleting emails from a junk folder. It seems to be events happening quickly that ether Thunderbird or Dovecot don't keep up with, so think the state of the message hasn't changed, so recreate the message maybe? I'm not really sure, so was hoping someone else had experienced the issue or could shed some light on it.

Thanks

Tim

The logs from when I managed to recreate this manually this morning as a test.

Some older logs from what I believe was deleting from the junk mail.
