best_mx_transport (default: empty)
Where the Postfix SMTP client should deliver mail when it
detects a "mail loops back to myself" error condition. This
happens when the local MTA is the best SMTP mail exchanger for a
destination not listed in $mydestination, $inet_interfaces,
$proxy_interfaces, $virtual_alias_domains, or
$virtual_mailbox_domains. By default, the Postfix SMTP client
returns such mail as undeliverable.
Specify, for example, "best_mx_transport = local" to pass the
mail from the Postfix SMTP client to the local(8) delivery
agent. You can specify any message delivery "transport" or
"transport:nexthop" that is defined in the master.cf file. See
the transport(5) manual page for the syntax and meaning of
"transport" or "transport:nexthop".
However, this feature is expensive because it ties up a Postfix
SMTP client process while the local(8) delivery agent is doing
its work. It is more efficient (for Postfix) to list all hosted
domains in a table or database.
