Spam

We got a spam email early this morning. I'm admin, but I can't tell if others got it as well. Based on the From line, it looks as if this person is a member of our club. How could they do that? I sent it to the blacklist. Here's the source data.

Their email may have gotten hacked. Suggest to them that they change their email password.

Be careful that you did not inadvertently add your member's email address to your black list (check it).

This person is NOT a member, nor are they in any of our other groups. That’s the reason I wrote in. The email came from outside the club.

Ok, got it... So, yeah, just blacklist them then.

So I guess your original post was missing a "NOT" (it threw me off) :

it looks as if this person is a member of our club.

Yep
