Are you relaying your emails via another ISP?  Relaying is not allowed in most cases.

I cannot see a SPAM marker.

email is just set up thru our web hosting... im not sure about relay? how do i know if it is doing that?
JohnBusiness Consultant (Owner)Commented:
I noticed the Relay flag which is why I asked. If it is going through your web host then probably not.

Put your email domain in MX Toolbox and see if any issues come up.

I too cannot locate a spam marker of any kind. The destination host seems to have rejected the mail. Are all of these bouncebacks coming from the same domain? given the degree to which you've restricted the addresses, I am unsure. However, if an inter-ISP relay is set up, then I am with the gentleman above in stating that relaying is usually "outlawed" in the mailing community.
SHFLTDAuthor Commented:
here is what i got when i put in our mail.<ourdomain>.com      


https            The Certificate has a name mismatch       
dmarc            Missing or Invalid Record       
dns            Local NS list does not match Parent NS list       
dns            Name Servers are on the Same Subnet       
dns            SOA Refresh Value is outside of the recommended range       
dns            SOA Expire Value out of recommended range
Chris KonickiSecurity EngineerCommented:
It may also be worth noting that the certificate for the aforementioned relay is due to expire before October. That may cause issues. Also, SMTP and DNS are having some resolution conflicts. Now, as for the issue at hand, there could be any number of issues that are causing your bounceback. I'll await your response.
JohnBusiness Consultant (Owner)Commented:
I am not exactly certain but you should ask your ISP about "A" records.  Look at the information in the documents below.

Then put your domain in:   http://www.dnsstuff.com/

It appears the mail server is not properly set up for your use (and that is over my head)
