@timfam it's hard to help with this without having the email settings (you might want to paste them here, not the password apparently...)
moving to discussions as I'm not sure this is an issue of MediaCMS or settings. Let's see the settings and find out!

Issue resolved, I was using port 587 instead of 25 and my email server refused connection. Thanks
