This should be a good release.:)

Would this release address the "reappearing emails" issue that 2.2.23 introduced?

I guess you're talking about replication. I'm not aware of any specific change in v2.2.23 that could have even potentially caused it. I also don't know how I could reproduce it. Can you use git bisect to find out the specific change that broke it?

The only thing I remember even remotely related to this ishttps://github.com/dovecot/core/commit/950a6e61d6c2dac961ce031bdd8b2895bc32b... but that was supposed to only fix things and I can't think of how it might break things.

One possibility is that nothing broke this in v2.2.23. I've heard about the same issue for a long time. Maybe you just suddenly started having this problem now and it would have happened even with the old Dovecot version.

I was (perhaps one of) the people who reported "reappearing emails" with 2.2.10 in the context of Maildir with replication under CentOS 7. I had spent a great deal of time making it reproducible, difficult because there was a timing element. In that context, 2.2.23 absolutely fixed the problem which was absolutely related to a timing issue with replication. If I remember right, this person was reporting a similar-sounding problem, but it did not involve replication and was not under CentOS 7. Creating a script that reproduces the problem is an important first step. Good luck.
