Hi All
Was just trying to understand something and am getting conflicting results..
If I set the following (or 2 mx of the same priority with 2 differnet a records)
Mydomain.com MX 10 mail.mydomain.com
Mail.mydomain.com A 10.1.1.1
Mail.mydomain.com A 10.2.2.2
I understand that will provide dns roundrobin but what happened if I shutdown 10.2.2.2, will I lose (logically) 50% of my mail as I do not have another fallback MX??
My understanding is that it does so as the sender mail server will cache the MX record and A record and will only send to there, am I right or am I getting this wrong?
If I'm shutting down 10.2.2.2, will the sender mail server retries to 10.1.1.1? (lets assume there's no ttl reconfig to zero)
Thanks lots
Thank you and have a splendid day!
Kind Regards,
