Sorry for delay @DocFraggle I’ve been rebuilding my desk, too. I have an entire procedure for updating mailcow, but it doesn’t include backing up the compose file. (It does now!)
I just ran the update script like I did the last time. I suspect you’re indicating I changed my file, otherwise it would have just gotten overwritten instead of maybe attempting to merge. The ONLY reason I can think of is that I may have disabled the “solr” search stuff from running. We don’t use it as a long-term IMAP store, only to send, receive and have Gmail pick up everything. (We don’t really use the UI, other than for admin. In fact, I wrote my own quarantine release and virus-laden delete that interacts with the IMAP and API directly. (I wanted to be able to manage multiple boxes at once, as well as not have to delete (or release to inbox) single emails at a time. (Which, last I checked, was how you had to do it.)

I appreciate the help, everyone!
