Hi All,

If I create two different IP address (A) record for the Linux appliance in my internal DNS server and then make it the same name like below:

External AD-Integrated DNS server:
mail.domain.com (A Record) 202.43.252.167 Default TTL 1 hr.
mail.domain.com (A Record) 202.43.252.91 Default TTL 1 hr.

Internal AD-Integrated DNS server:
mail.domain.com (A Record) 10.1.1.100 Default TTL 1 hr.
mail.domain.com (A Record) 10.1.11.113 Default TTL 1 hr.

PRODMAIL01-VA.domain.com (A Record) 10.1.1.100
PRODMAIL02-VA.domain.com (A Record) 10.1.11.113

Would that configuration works for the Exchange Server 2013 Send Connector resiliency if I just put mail.domain.com ?

So if I need to perform maintenance or upgrade on the Virtual appliance, I can just delete the (A) record and then retype it again once it is done, without causing any email queue or blockage.

My assumption is that the TTL in the public DNS can be reduced to just 1 minute to expedite the process when the email is queued during the appliance maintenance.

Any help and comment would be greatly appreciated.
