Question
1) Is there a way to tell the secondary MTA to check with the primary MTA if the mail will be accepted or not (assuming the 1st MTA is available) ? (I guess I may create all accounts and forwarding rules for each of them, but this will not be maintainable).
Nope.
2) Is there a way to tell the 1sr MTA to give up after a certain number of attempts to return the message ?
The default timeout setting is one week.
