Sorry to kick this old topic, but I'm trying to use GMail as SMTP server. I've copied Sanchez code to ezsmtp.php but i can't get the email notification system to work. In site.ini.append.php i've put the following settings:
[MailSettings]
Transport=smtp
TransportServer=smtp.gmail.com
TransportPort=465
TransportUser=********@gmail.com
TransportPassword=*******
AdminEmail=********@gmail.com
EmailSender=********@gmail.com
I'm getting the following error in the logs:
Unable to connect to SMTP server smtp.gmail.com I'm running ezpublish version 4.1.1. Is there anyone who got gmail to work with ezpublish or can help with the right settings?
