Postfix - how to reject numeric domains.
I would like to set my postfix to reject any numeric domains. I am seeing in my mail queue mail from domains like 2212.com, 263.com, 29.com and others. Because there is a variety of these, I don't want to track each of them and block them one by one.
What do I need to put in my access file to reject any numeric domain? Is it posible to have a numeric wild-card reject in the access db?
