SMTP email settings

I have tried using localhost port 25 on every possible environment but do not ever receive the email the application is supposed to send. The application believes it successfully sends the email yet I never receive it. I do not put a username and password in my SMTP settings and I set SSL to false. Shouldn't this work? Can anyone provide me with a little more information than the last thread I made?

try sending an email on your local development environment using the smtp settings, username/password from for example gmail (if you have a gmail account).

This way you can monitor what happens and check if the module can send an email.

If this works, try applying these changes on your acceptation and production server to see if email is still being send.

if so, your previous settings where wrong! or the smtp mailserver used is blacklisted?
