postfix not sending to host
Posted: Fri Aug 08, 2025 12:47 pm
Hello,
I used to use postfix to send mails directly to another server,
But since the last update it is not working anymore. The mails get bounced (on the sending server).
The SERVER is in the /etc/hosts file, ping works.
Why is it looking for DNS entry ?
