MX records
Hi all,
We have a couple of domains running as secondary MX (backup MX).
domain.com. IN MX 10 mx1.domain.com.
domain.com. IN MX 20 mx2.domain.com
mx1.domain.com is the primary mail server.
mx2.domain.com is the secondary mail server.
mx2.domain.com is pointing to a loadbalancer with 2 mta's behind it (mta1.dom.com and mta2.dom.com).
When mx1.domain.com is down all the mail is received by mx2.domain.com (which are mta1.dom.com and mta2.dom.com).
These mta's are trying to connect to mx1.domain.com because that is the primary MX but this is failing because mx1.domain.com is down. After this the mta's are trying to connect to mx2.domain.com but this is not correct because there are connection to it selfs (through the loadbalancer), this is also failing because they can not connect to the loadbalancer otherwise the mail will loop.
How can I prevent the mta's to connect to the mx2.domain.com, in other words how can I configure the mta in a way it also knows it is mx2.domain.com?
Kind Regards,
Bas Toonk
