Failover internet connection for email server
Expert Folks,
I currently have Verizon as ISP and we plan to use Time-Warner for fail-over. Both have static IP address. I am using Barracuda for router, have the capability for fail-over. Can someone please guide me where to begin setting up Failover internet connection for email server.

Hello max_the_king,
Okay, we did you recommendation, however we noticed some delay on emails coming it. Below are the steps.
1. add new A record with the new ISP.
2. add MXRECORD with higher priority rate of 20.
3. check MX record propagation using mxtoolbox. TTL is too high (120mins)
4. Run failover test.

question on set multiple MX records with different priority:
email.domain.com 10
email.domain.com 20
is this correct?
email.domain.com 10
email.domain.com 20
is this correct?
mx should be different if they come from different isp
But if you have 2 mx you need 2 barracuda appliance.
with 1 barracuda you may manage multiple domains but One and only mx.

Hi,
it is well explained in the following link:
https://techlib.barracuda.com/usingmxrecords
basically, best practice for using 2 MX records is to have 2 Barracuda appliances (each of them will be static natted and respond on port 25 with its own public IP address).
hope this helps
