Don't know why my more lengthy explanation did not meet community guidelines.  I am getting spammed with SMS messages sent from email addresses with pointless links that are not actually working links.  I want to disable messages from Email adresses on an iphone.

We understand how annoying those spam messages can be, @james_russellhsbcom. 

In order to look into your messaging preferences, we'll have to carry this over in a DM. Please check your Direct Message inbox (it's the chat icon next to the bell icon in the upper right corner of the Forums).

In the meantime, here's a few things you can do to help us combat the spam epidemic: 

• Forward the text content to 7726 and then report this 10-digit number as the sender: 1410100000. Our systems will be able to look up the sender’s email address, allowing us to take appropriate action.
• Report suspicious text to the FTC. 
• Report suspicious text to the Anti-Phishing Working Group.

Protect yourself from text scams by remembering these tips:

• Don’t rush. Pay attention and read the message carefully. Bad guys will create a false sense of urgency by implying an immediate response is required. Don’t fall for it. If you are busy, don’t do anything with the message until you can really evaluate the authenticity.
• Don’t reply. Even if the content is lewd or inappropriate, do not reply to say stop sending me messages. Responding to the text verifies your phone number is active and shows you are willing to interact, which may lead to an increase in the unsolicited text messages you receive. And certainly, never send personal information to a suspicious text. Do not reply. Just delete the message. If you get a reply from someone else in a suspicious group text, do not reply to them either. Each reply just keeps the group text thread going. Delete it and move on.
• Don’t click links. If you don’t know the sender, don’t open any links to websites or content they may include. This could lead to fake websites or allow malware to infect your device. If the message looks like a sender you know, and it says that you should click a link or call a number, don’t call or click. Instead, call the customer service number on your regular bill and ask if the message is legitimate. As in the case above, it may be an attempt to get personal information or scam you.

Reminder: We'll be chatting with you soon to address this matter, so please keep an eye out for our DM.

The link for the Anti-Fishing Working Group posted above gets a 404 error: https://forums.att.com/conversations/account-features/sms-messages-from-email-addresses/[email scrubbed]

Would you update that link if it is an appropriate place to report spam SMS/MMS received from an email address.
