Club 1196053 - Spam eMails that don't have eMail address that can be blacklisted

I think they are scammers who somehow found the FTH generic email addresses.  I've gotten a couple that say "Your Personalized Social Security Statement is Now Available" but, as mentioned earlier, can't be blocked.  The sender is:  suhendi.andigo@prosa.ai; on behalf of; Toastmasters Club 2207975 on behalf of SSA Records Office .  2x.  It's only a matter of time before they figure out the structure of our email addresses and just start spamming with scam emails like crazy.  In this case, there IS an email address, but for some reason FTH is not catching it and allowing it to be blacklisted.  The double "on behalf of" seems to be a spoofed display name that the scammer set up.

I tried sending to this address from a different email account, and what I received was more properly structured, but I still got the can't block message.
Mary Mattran, DTM,
was NOT successfully added to your club website black list.
It may not be a valid email address. Also, you cannot black list yourself, and you must be a current club member to use this function.
You can close this window now.

mfmattran@yahoo.com is absolutely a valid email address.  And, it is not the email I use for my TM stuff.  So, I'm confused...

This one went to club 2207975.  I also belong to 1520707.  VPM & VPE respectively.

Always look at the email headers, it will tell you exactly who sent the original email and the IP address it was sent from.
