I'm preparing a move from our online provider e-mail to our own cloud hosted Microsoft Exchange Server.
I'm looking at our current DNS records in the provider config panel regarding email:
- MX , mail.mydomain.com
MX , mail2.mydomain.com
A mail 126.96.36.199
- A mail2 188.8.131.52
- A pop 184.108.40.206
What's interesting to me is that the secondary mailserver is the same as the primary. Could there be any use for this?
Seams to me like when the primary is down the secondary is also down right? So I have no clue why this second mx entry is in there?
So I'm wondering can I just remove that second entry? Then I'm only left with the first entry and I will point that one to the new mailserver. (for now we only have one mailserver)
Can anybody confirm the usage of the second MX record and if I can just remove it. (along with its A record)
