We do not filter email the the officer email addresses, so yes you will receive spam to these email addresses.
If you post the internet header we can see where the email originated.

Hello Brian,
If you are saying it is indeed spam, that is fine with me and I do not care where it came from. However, if you want to determine the origin, I'll be happy to retrieve it, if you tell me how to get the Internet Header.
Thanks much for the quick response!

Did you click the spam link at the bottom of the email?
If not do so on the next one.

Hello again Brian,
Thanks very much for your patience. Here are the two links at the bottom of the message alerting SPAM possibility.

...sender's email address (mail_delivery40@s1.valueserver.jp)
Web Page: https://3926.toastmastersclubs.org?blacklist=00778505-mail_delivery40%40s1.valueserver.jp

Yes those are the links to block email from that person.
