I want to ask around the other members if anyone has any experience with pre-verifying email addresses without actually sending anything to them. I was looking into whether we could leverage pmta to achieve this, but the support team tells me not.
From what I understand they just initiate the connection, wait for the recipient mx server to respond, and then terminate the connection. Apparently this works for everyone except Yahoo.
Have you seen PMTA being used for this. If not any pointers in doing this en masse? Script examples perhaps. Or any general experiences?
We want to use it as a part of our compliance testing and on-boarding processes.
