Hello,
Can you please contact your ISP and double check if port 25 is allowed to be used?
Virtualmin is on a VPS, and I’ve another VPS on the same server host that works with postfix. How can I configure Virtualmin mail on a different port?
Thank you.
Regards.
I assume both VPS’s have different IP addresses - if so Postfix should be fine on both (using the same port\s).
We need to see the relevant mail log entries. The client does not have useful information about why it failed.
