Hello All..........If following is my MX Record Configuration:
10 mail.abc.com 1.1.1.1
10 mail.abc.com 1.1.1.2
20 mail2.abc.com 1.1.1.3
30 mx2.isp.net 1.1.1.4
Can someone explain how this might be working? How traffic would be coming in? in case of failure of one how things would be moving forward?
