Can I stop a blacklisted ip address from doing RCPT command. I have Mailscan for SMTP?
Solution:
Yes. To stop blacklisted ip address from doing RCPT command when using Mailscan for SMTP, follow the below steps:
1. Start the Windows registry (you can refer to FAQ - How to start the windows registry editor?)
2. In the registry key,
