Comment (by essandess):

 Not a bug, a dovecot+macOS feature!

 It’s discussed in the dovecot mail list. The large number of groups
 defined in macOS crosses some dovecot threshold, resulting in the auth
 failure.

 You can raise the issue upstream, but my expectation is the response will
 be that it’s not a bug, but a configuration issue on macOS.

 Also, your fix doesn’t make sense to me. I believe the fundamental issue
 is group id’s (gid’s), not user id’s (uid’s). AFAIK there are no macOS
 gid’s above 1000. Does this configuration turn off all valid gid’s? Run
 this to see all your gid’s:

 {{{dscl . -list /Groups PrimaryGroupID | sort -n -k2}}}

 Would you please check your fix and compare to the dovecot mailing list
 discussion/dovecot code on github? If necessary, we can patch the dovecot
 code in MacPorts so that it doesn’t tickle this issue.
