As a FYI, on RC4 I was having an issue with local mail. I created a PR and the PR was just fixed.
If you are not receiving mail on your local system from local users, this PR will have the fix. You will need to update File /etc/postfix/main.cf and restart mail.

This is the fix Martin posted to the PR:
