Invalid / Nonworking Address

I had reported an issue with dhardie@cre8ivecommunications.com email address a while back. I am getting a different message but same effect. No email being sent to his email address. Getting message Invalid / Nonworking email address.

Is it getting blocked again. Brian had graciously unblocked it last time. Hoping it is the same issue.

I got the error message today. I tried to send him an agenda in the last hour (twice) and it gave me that error message.

He has indicated he received emails from one of his other clubs yesterday fine. But, did not get the agendas I sent in the last hour.

We are not blocking his email server, I believe his server is blocking FTH email.
You will need to get him to check.
