I have just loaded up the core using Arvixe 1 click connect. No changes, as just wanting to learn the system. Tried to set up a profile and the emails are getting rejected:
If your emails aren't being received by Yahoo Mail accounts, here's information that should help you understand why this is happening.
Why you're seeing this error
Your message wasn't delivered because Yahoo was unable to verify that it came from a legitimate email sender.
Your email failed one or more of the following industry-wide authentication checks that Yahoo uses to verify emails are truly sent from the domains they claim to originate from. Click an authentication method's link below to learn more.
SO: What am I doing wrong?

. You will not be able to send email until you have setup a domain on your account and have properly configured reverse DNS for your domain. You will also need to setup an SPF record and (possibly) a proper DKIM (domain key). Arvixe can assist you with all of this - it's not something Jamroom has control over - it has to be setup at your domain level.
