Smtp relay set issues

Community Support Mail

Hello,

I have set up a separate SMTP server on port 2525 with no encryption (secure: none). I also tried adding this SMTP server as a relay in Hestia, opening port 2525 in the firewall.

However, only ports like 587 (TLS) or 465 (SSL) seem to work. How can I configure the system to use the non-encrypted SMTP port (2525) for the relay setup?

Do you have any guide or configuration steps to make this work?

Thank you.

You don’t need to open port 2525 for outgoing traffic should work fine

Use following settings like this and it works without any issue

I have added the SMTP multiple times, but it is not working. My SMTP on port 2525 does not support TLS or SSL. However, the SMTP works fine with other tools and websites.

Can you provide a solution for this issue?
