jkchapman@mountprospect.com issues - I have a reply from MountProspect.com Admin

Please contact Tom Nelson <tomn@bytemeusa.com> of Byte Me! Web Hosting and Design. He wrote Kevin, who forwarded the email to another member and me - but the attachments weren't forwarded: The text of his message:

I spent some time on this because not only do I want to provide good service to you I have an obligation to all my clients.
I saw the first 2 lines of Brian McDonald’s response and would like to see some evidence of spam sent to FTH.
I reran the checks Steve James provided and attached results to this email.

I also attached a few other tests. MXToolBox.com results for MX, SMTP and an email header analyzer.
Ran a test with mail-tester.com for SpammyNess.
Check multiple Blacklist and Reputation websites, none of which we are listed on.
Finally, double checked to make sure we weren’t greylisting incoming email for you and we are not.

If our server if blocking the server their bulk mail comes out of, then I would need the IP of the source to whitelist it in our system.
If it has something to do with DMarc, DKIM, SPF or the like I would need to domain of the email address that sends bulk mail to you.
Feel free to forward any of this to Brian, Steve or anyone else you think may be interested.

Please don't Close this until its been resolved. If one of Tom's attachments gets forwarded to me by Kevin, I Want to have a place to attach them in my reply.
Thank you for your patience with me regarding this matter. (Did anyone from Career Communicators report it too?)
