[dmarc-discuss] Third party host email and DMARC

Hi Jerry,

smpt5.volusion.com is almost certainly incorrect and you likely want it to
be *smtp5.volusion.com <http://smtp5.volusion.com>.  *What you have
indicated in your record doesn't exist in DNS and would certainly result in
the mail from that server not being authorized.



Cheers!
Todd
