is there a good article/video explaining how to set up SMTP properly with S2member?
Cant seem to make it work

The SMTP debugging output is shown below:

2015-11-12 17:44:24 Connection: opening to localhost:25, timeout=300, options=array (
)
2015-11-12 17:44:25 SMTP ERROR: Failed to connect to server: Network is unreachable (101)
2015-11-12 17:44:25 SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

sorry ignore the last paragrpah of my previous post

I m using a registration Pro form but for some reason the email sent has nothing to do with what i config and keeps going to the spam

Gmail is telling me that this email is going to spam cause it s been sent by gator4197.hostgator.com

thx
