    Been running for years old debian so did a fresh install of debian 10 on another system and did fresh install of ispconfig 3 as well. Followed How to Install a Debian 10 (Buster) Minimal Server and The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1 instructions. I did not notice any errors when installing.

    I am mostly a builder and repair on systems so every time I do an upgrade I have to learn my way around the system again so any help is greatly appreciated


    I have tried many of the threads here but none seem to work. This is a fresh install of Debian and ispconfig 3 following the howto instructions. Any ideas why this would be happening on a fresh install.

    Have you check if you have your firewall blocking the port 25? because in your message the first thing i notice is that port 25 it can't be reached

    And in my limited knowledge as far as i know that port is used for the SMTP services.
