Currently I have 100+ EMails queued with "Network error on destination MX". This is a severe regression since OpenBSD 6.6.Every insightful comment is highly appreciated
Please show your complete config file. Maybe it has an error.
My current (new-style) smtpd.conf has a lineaction "relay_external" relay src 192.168.1.1 helo "mail.example.com"
Does your original config has a private IP-address too? Maybe you are behind a janky NAT router?
