$CONTACTEMAIL$ Macro...where does it come from?

I am trying to setup email notifications for more than one contact and cannot seem to get it working. My default setup with a single contact works like a champ so it is an issue with how I am trying to use contact groups I believe.
What I am not clear on is the process how an email for the $CONTACTEMAIL$ Macro used by my email notification comes from. I have two different contacts in my contacts.cfg, who are then assigned to contact groups in my contactgroups.cfg file. From there I have the contact group specified in the services.cfg for the services that I want the other person to receive emails for. Triggering some test alarms yields no emails so I am not sure what is going on.
Any clarification or direction would be appreciated...

You should be able to just copy or duplicate your working contact, and change the copy's name and address in the configuration file, then add it to the contact group. That macro pulls the address(s) you give your contacts when setting them up:

Agreed...it should be that easy, and this is what I have done, but it is still not working. There is a piece in the chain that is not configured correctly on my part and I am probably not presenting all the information here.
My Host check uses the following command: check-host-alive
$USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
Now I am getting emails for this check when it fails. I don't see how since I cannot see where an email address or macro is specified for this check. This part of the reason I am confused but I think I am starting to narrow it down.

The macro is from a contact, which most likely was inherited from a contact group, host, or hostgroup. Can you post the configs for this host, one of its services, both contacts, and the contact group? (obfuscate emails/etc if you wish)

the contact email is being pulled in via a path that would look something like: host\service->contact group(admins)->contact(nagiosadmin)->email(gsmith..company.com). When nagios calls the notification command associated with your contact due to an event needing a notification sent, it simply pulls the email address out of the contact information and stores that in the macro structs used for such things.
Is it your gmail contact\address that is not working properly? If so, most likely this is due to either your local mailer, used by notify-host\service-by-email, forwarding directly to your internal server which denies it based on not allowing mail relaying.(perfectly normal and standard setup) It could also be that your ISP is set to deny outbound smtp connections, less likely if you are on a commercial line. Finally it could be that gmail is not allowing you to communicate with them directly, not normally the case if they suspect something is up they usually just put your mail in spam.
With all that, I would look at how your local mailer is setup, such as to forward just to the internal server, and either alter the mail server it is sending to, to allow nagios to relay through it, or correct the local mailer so that it sends to a gmails mail servers if that is the destined domain.
