SPAM Emails from Domain

Over the past few weeks, we have been receiving a large amount of SPAM to our club inbox directed from server@toastmastersclubs.org. As an IT professional, this tells me that someone has launched a phishing or spoofing attack on the domain. I have been blocking and adding the offending domains to my clubs blacklist as I have received them, but may need more support to properly block these emails. I have also raised the SPAM guard on the FTH site higher and that did not change anything with respect to receiving these malicious emails. I will include screenshots of the emails and domain information for you, and need to know if there is anything you all can do to assist or should I just continue to fight it the way I have been.

I am including a word document with the screenshots. I will be blocking them on our end, but after talking with Google, it looks like the issue is passing through the domain. I have trimmed some of them as the contents on a couple are highly inappropriate. Please let me know if you can assist.

Club Number: 7757
Club Name: Austintatious Toastmasters

I see you are using the tools we provide. I suggest you block the entire domain @domain.tld

Private Message me the IP addresses that are the source of the emails, and we will shut out the mail servers that are being used.

Give me a bit and I will send that over to you. I am trying to send over the screenshots and the forum won't take my uploads. So I will have to get it the hard way.

I am trying to upload the documents to you but I am getting a "Failed to create attachment directory" error.

Yes we know, that is why I asked you to pm me the email IP addresses
