Sorry if this is a nubbie question, but I’m getting:

lda(jlbrown@bordo.com.au)<4444><QFg5KRHVBBxcEQAAYBwt+A>: Fatal: setgid(102 from userdb lookup) failed with euid=501(jlbrown), gid=20(staff), egid=20(staff): Operation not permitted (This binary should probably be called with process group set to 102 instead of 20(staff))

How can I fix this?

(macOS Mojave, Dovecot 2.3.4)

Thanks,

James.

You need to tell your MTA to execute dovecot-lda as the target user as you are using per-user UIDs.

Thanks Aki.

It works now. Not sure what it was.

In Postfix’s master.cf changed the user in the dovecot line.

Also changed dovecot/auth-userdb user and group, and permissions.

Anyway, all works now.

Thanks again,

James.
