Nov 3 12:23:05 desmond dovecot: lda(granitemon): Debug: Effective uid=1003, gid=1003, home=/home/granitemon
Nov 3 12:23:05 desmond dovecot: lda(granitemon): Error: setegid(privileged) failed: Operation not permitted so it's running as the normal user, and NOT with the mail group. I'm using exim with LMTP. LMTP is NOT a bad thing, and might make your life easier. It does allow you to add sieve scripting if you want to via pigeonhole. Sorry, I'm at a loss, as I do NOT run postfix. I'm not sure what it needs to invoke dovecot-lda with gid mail in the group list.
