email address appears to be blocked from sending to clubs

My email address jonathangoossen@comcast.net appears to be blocked from sending to any FTH club address. Last work on 9/4/2019. First issue on 9/17/2019 to home club members. I found out yesterday that it is blocked when using club FTH contact us forms for clubs that I want to visit.

447 is a club I have never visited or contacted before. I showed up last night to find the club didn’t meet.
4043570 is a club I helped start a few years ago. I contacted through the international find-a-club. This morning I had a warm reply. They remember my earlier help and invited me to visit whenever I want.

It doesn’t look like any of the three clubs would have black listed me.

I have attached the text that was attached to one of the replies. I have added an attachment for the text to one of the clubs from their FTH site (email_156939578832824).
Please let me know if there is any other pertinent information needed

Thank you and have a Terrific day!

In that code, it stated that it was sent.... Did you send from work? Either that, or make sure the email address you are sending from, is in your address book and attached to your email account.

The ones to my home club are sent from my personal email using my personal system. The ones to other clubs are from their FTH site. I'll see if I can attach one of the other club attachments

I don't understand your last sentence. the email address I sent from is my email account. Why would i need my own email address in my own address book? Please explain.

I apologize... I thought at first your email address was a .toastmaster email address. I will let someone else answer your questions then... I was thinking also, maybe it is a comcast issue...

I reactivated an email address I used as a district officer and added that to my profile for my home club. It works fine. It is attached to the same Comcast account that the problem address is the account ID.

Any other things I can test?

I will let someone else handle this now....
