[Dovecot] Can't drop root group privileges

An update on my problem dropping root group privileges. I
discovered this is a problem for a user if they are in the
system group (gid 0). If I remove the user from the system
group, and leave them in their primary group, I don't see
I've tried setting first_valid_gid to something like 4, hoping
dovecot would filter out gid 0, but that doesn't work.
Still searching for an answer...
