https://github.com/OpenSMTPD/OpenSMTPD/issues/1200I am facing the issue above exactly as it is. What is smtpd, and smtpq wrt users. I have given all permissions and added them to mail group but still I cannot remove the error msgs.
The secondary/supplementary group (mail) of your users don't count in this case. Only their primary group. Simply give others read access:
# chmod 755 /var/mail
