dying on osx

Mike, I’m having the exact same issue on macOS X 10.13.6 (High Sierra). I’ve installed Dovecot using Homebrew.
The number after ‘Setgroups’ is the Group ID of the user you’ve specified.
Log entry for me:
Aug 28 11:57:21 imap-login: Info: Login: user=<user1 at bordo.com.au <mailto:user1 at bordo.com.au>>, method=PLAIN, rip=::1, lip=::1, mpid=57665, secured, session=<V7GIJ3V0//MAAAAAAAAAAAAAAAAAAAAB>
Aug 28 11:57:21 imap(user1)<57665><V7GIJ3V0//MAAAAAAAAAAAAAAAAAAAAB>: Fatal: setgroups(mail,6) failed: Too many extra groups
Aug 28 12:00:45 master: Warning: Killed with signal 15 (by pid=71449 uid=0 code=unknown 0)
I managed to get it to work my changing default_login_user and default_internal_user to me my username.
Obviously not ideal!
However it was the only way I could get it not to give the setgroups error.
I spent ages trying with _dovecot and _dovenull to no avail.
id _dovecot
uid=214(_dovecot) gid=6(mail) groups=6(mail), … and a few more
id _dovenull
uid=227(_dovenull) gid=227(_dovenull) groups=227(_dovenull),12(everyone),61(localaccounts),703(com.apple.sharepoint.group.3),702(com.apple.sharepoint.group.2),701(com.apple.sharepoint.group.1),100(_lpoperator)
Dovecot 2.3.2.1.
Thanks,
James.

I suspect that dovecot is adding a number of groups when it starts up.
