Have you considered the following:
- Inbound mail spends a fraction of a second in the queue.
- Inbound mail spends days or weeks or more in the mailbox.
- If an MTA goes down, mail flows via alternate MX hosts.
- If the mailbox store goes down, then you have no mail.
That's why high availability focuses on the mailbox store,
not on the MTA in the middle.
[talking about OUTBOUND mail which was not the subject of this thread]
You change the topic of the discussion and then claim some
contradiction.
Not to be argumentative or anything, but... original query was:
"Presently we have primary MX and backup MX servers, when primary goes
down mails will be queued in secondary MX, once primary restored all
messages pushed from backup MX to primary MX, messages are not lost. I
would like to know any solution sending and receiving messages from
backup MX when primary MX is down?"
Which sure looks like it includes outbound ("sending") as part of the topic.
