Wrong mailing list. You need to ask on the list for the MTA you are
using (Sendmail, Postfix, &c).
Actually, this sounds like a job for a custom milter, which would look
at the domain name of the sending system, and reject the mail with your
message. Dunno if there is one that works exactly like this.

I am sick of this gmail spam. Does anyone know a solution where I can do
something like this:
1. received email from adcpni...@gmail.com
2. system recognizes this email address has been 'whitelisted', continue
with 7.
3. 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.
