Connection refused on http://SERVER-IP:8025

Hi !

I've just install Mailhog on a debian server.

When I launch the service, all is ok to send email, and the localhost:8025 interface is OK when I test it with the command "lynx http://localhost:8025".

But in Chrome or other, the url with the server'ip don't work : http://SERVER-IP:8025 

Thank for your help :)
