Postfix will send A and AAAA queries, but it will report an error
only for the last query that it tried. You might fimnd more details
in the Postfix logging.
So, the complete error message would be :
"I made DNS queries with type A and AAAA for the name
another-example.com.mail.protection.outlook.com. All queries
failed. The last query that failed had type AAAA. The last error
was "name exists but there is no AAAA record".
But we reall don't want to send THAT in an email bounce message.

All A and AAAA queries failed.
