I worked with tech support at CrownCloud. They had me disable ipv6.
- Remove the ::1 line from /etc/hosts
- Change inet_protocol in /etc/postfix/main.cf from ‘all’ to ‘ipv4’
Then the test echo “test” | mail -s test firstname.lastname@example.org worked.
However, I could not get the SMTP relay via gmail working.0
