Yeah, sure... here they are.
I have scracthed a lot of things, since I don't know exactly what is not safe to show in public
I'm also deleting the allowing everything rule for now, since I don't think it's safe to maintain it there.
The settings are configured this way:
SMTP server: smtp.zoho.com
I was not able to upload both images here, that's why I writed it all above.
Also, this is the error I'm getting every time I try to send a test e-mail:
Connection could not be established with host smtp.zoho.com [Connection timed out #110]
