I love this add-on, would be even more happy, if it would work. Avaliado em 4 de 5 estrelas
I installed the latest version yesterday, sadly do not receive any delivery notifications.
Your SMTP server does not support DSN
This add-on only adds UI settings for sending DSN.
If you do not receive any notifications, it's probably because your SMTP server does not support DSN.
In order to check that, create a telnet connection to port 25 of your SMTP server and type "ehlo test". The server should answer "250 DSN" if it provides DSN.
