Hello
I am currently thinking about implementing a fallback scenario for our mail-server.
Currently we are using two uplinks with static addresses. One is used for mail (via Multipath rule). The MX record points to an A record which resolves to this static address.
What I now want is the following:
mydomain.de MX 1 mail1.mydomain.de
MX 10 mail2.mydomain.de
mail1.mydomain.de A
mail2.mydomain.de A
The fallback line is configured for standby, so its down while the other line is up. If I understand MX-records correctly, this config would ALWAYS refer to mail1.mydomain.de unless mail1.mydomain.de is unreachable right?
So that would be a working Failover scenario that would also make sure that my domain doesn't get blacklisted due to wrong sender address right?
Thanks for you guys double-checking
