RE: handling spam from gmail.

Yes thanks, I know, however the criteria for putting emails into this procedure is a different subject. Just wondered what people are doing.

I am sick of this gmail spam. Does anyone know a solution where I can do something like this:

1. received email from adcpni444@gmail.com 2. system recognizes this email address has been 'whitelisted', continue with 7.
2. system recognizes as this email never been seen before 4. auto reply with something like (maybe with a wait time of x hours): Your message did not receive the final recipient. You are sending from a known spam provider network that is why we blocked your message. Please confirm that:
   • you are not a spammer and
   • you have permission to use the mail adress you send your message

to

• you and your provider agree to uphold GDPR legislation
• you and your provider are liable for damages when breaching any of the above.

Click link to confirm and you agree with the above https://www.domainwithoutletsencryptcertificate.com/asdfasdfadsfaf

5. sender clicks confirm url
6. email address is added to some white list.
7. email is delivered to recipient.

If you do this rgularly enough, sending these messages to what are likely forged return addresses, you might just end up being classified as a spam sender yourself.
