my first question i suppose is to know if anyone can link to the software i have a slight knowledge of which does the following:
- intercepts new emails destined for a target account
- determines if the address is on a whitelist
- if not, it automatically sends a message back to the sender that prompts them to reply to that message with some type of “verification code”
- sender replies with correct verification code (which i assume is random) and are added to the whitelist
- original email is, only then, delivered to the target account
part two of this question is to know if dreamhost has anything like this set up?
