mail2.siteamerica.com doesn't seem to recognize your domain and it's listed
as your MX record.

Using your MX 10 mail host:
> RCPT TO: <root@xxxxxxxxxxxxxxxx>
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)

On another try, it went through relay5.exodus.net and appears to work:

--- verify e-mail "root@xxxxxxxxxxxxxxxx"
--- looking up mailexchange for gwinnetthome.com
--- contacting nameserver 24.2.3.33 (24.2.3.33)
--- found mailexchange "relay1.exodus.net"
--- contacting host relay1.exodus.net [206.79.240.116]

Other tries randomly hit various exodus.net relays and some reply connection
refused.
Others just time out.
