Let's suppose that system-generated mails all will have

If I send this system-generated mail:
user$ echo test | mail -s test [email protected]
I would like to have it delivered directly, without any relays (as it
will come as [email protected]).
Don't specify relayhost in main.cf.
However, if external users connect to send mail through this Postfix
server, they need to be relayed through a different host.
This requires Postfix version 2.6 or later.
Use sender_dependent_relayhost_maps. Return DUNNO for
[email protected], and mail.isp.net for everyone else.

According to that documentation page, "sender_dependent_relayhost_maps"
is "is available in Postfix 2.3 and later" - you mention Postfix 2.6 though.
Is this a documentation typo, or is "DUNNO" only supported as of Postfix
2.6?
I run Postfix 2.3 on this machine.
