Can you try turning on mail_debug and see if you can reproduce the duplicate email issue?

Hi,
I haven't received any responses to my duplicate messages problem. It occurred to me that I posted my full dovecot config instead of just the changes we've made locally. I thought it might help to follow up with just the specific config to make it easier to identify a potential problem.
Any ideas greatly appreciated.

Hi,
I have a fedora28 system with dovecot-2.3.5 and I'm trying to figure out why I'm increasingly receiving duplicate emails. The message IDs are exactly the same. It's always two of the same messages. I don't think it's ever occurred in the inbox. It doesn't happen with every message or seemingly in every folder.
I've read about dovecot deduplicate, but of course I want to prevent them from being duplicated in the first place. It's also happening much more frequently now.
Could something in my configuration cause this problem?
