I assume you have configured the zone of test1.com in Peplink properly. Also, the “mx.test2.com” is point to the actual mail server and it is a valid A record which can be resolved in Internet.
The test1.com domain zone is already configured but when I am configuring the MX, I can not enter mx.test2.com because the domain is being generated automatically to test1.com. I am currently using BIND for my DNS servers wherein the the test1.com domain contains the mx record of mx.test2.com. Appreciate if you can extend your instructions more in detail. thanks in advance.
Hi Chung-lai,
thanks for your support. I forgot to give update yesterday about the information I got regarding the “trailing dot” for a dns record on a foreign domain. This solves this issue. thanks again!
