Hi All,
Have a legacy server that I've just taken over maintaining. It's set up
with postfix that handles a small handful of email users. In looking
through the logfile I'll frequently see emails bouncing (and the bounce
messages being deferred so they just sit in the queue wasting retries).
How do I setup one secondary MX for two primary mail server? The two main ones
have different domains and settings. All three are postfix.
Thank you.

Sorry for inception.
How can I configure postfix to cause an instant message returned, rather than
4xx code to make peer MTA retry many times?
Thanks

For data HA purpose I backup all Maildir to

In the second server I run the same software

And in main.cf myorigin points to the file /etc/mailname.
But I don't see a config file /etc/mailutils.conf?

I have setup the domain in /etc/mailname, such as example.org.
but my hostname is something like sdfsfsdf.example.org.
When i send an email from terminal by "mail" commaind, the mail is sent via
postfix installed on localhost, the sender address appears always as
"u...@sdfsfsdf.example.org", not
It's probably backscatter:
