I have the following DNS setup:
MX 0 mydomain.com -> mail.mydomain.com
A mail.mydomain.com -> 10.10.10.10
Recently, my host of 10.10.10.10, changed my IP address without notifying me. All the email I had setup @ 10.10.10.10 broke. Actually I only use 10.10.10.10 for mail forwarding, but still it broke. Naturally I fixed it by changing this dns record:
A mail.mydomain.com -> 10.10.10.20
1. Is there a good monitoring service you guys recommend that would SMS alert me the instant one of my forwarding email addresses stops working, whether it is a problem with DNS or otherwise?
2. Is there a better way for me to setup my DNS so that I can avoid downtime in the future?
3. Is there a good professional email forwarding only service out there? I see Dyn has one, but I'm hesitant.
