To answer the question:

This information is overruled with relay_transport,
sender_dependent_default_transport_maps, default_transport and
with the transport(5) table.
So that is no good. But there is a solution:
You can override everything with the "FILTER transport:destination"
directive. With Postfix 2.7 and later, you can omit the destination,
so that Postfix will use the recipient domain as destination.
man 5 access
Note 3: the purpose of the FILTER command is to override message
routing. To override the recipient's transport but not the
next-hop destination, specify an empty filter destination
(Postfix 2.7 and later), or specify a transport:destination
that delivers through a different Postfix instance (Postfix 2.6
and earlier). Other options are using the recipient-dependent
transport_maps or the sender-dependent
sender_dependent_default_transport_maps features.
The FILTER action takes effect for all recipients of a message.
If a message has multiple FILTER actions, only the last one will
take effect.

Thanks so much for the reply.
I have tried changing the postfwd.cf rule from:
id=RULE-SIZE-RELAY; protocol_state==END-OF-MESSAGE;
sasl_username=~/^tes...@example.com$/ action=FILTER smtp:[127.0.0.1]25;
to:
id=RULE-SIZE-RELAY; protocol_state==END-OF-MESSAGE;
sasl_username=~/^tes...@example.com$/ action=FILTER;
and
id=RULE-SIZE-RELAY; protocol_state==END-OF-MESSAGE;
sasl_username=~/^tes...@example.com$/ action=FILTER smtp;
and
id=RULE-SIZE-RELAY; protocol_state==END-OF-MESSAGE;
sasl_username=~/^tes...@example.com$/ action=FILTER smtp:;
and
id=RULE-SIZE-RELAY; protocol_state==END-OF-MESSAGE;
sasl_username=~/^tes...@example.com$/ action=FILTER smtp:[]25;
but the postfwd log entry shows the message hitting the "id=DEFAULT;
action=dunno" catchall entry at the end.
I am obviously doing something stupid with my next-hop syntax or the
whole rule. I will try again tomorrow morning - it's late here.

The correct response from your policy service is "FILTER smtp:"
(without quotes, of course) ie. in "FILTER transport:destination"
leave the destination empty.
Looks as if you're having trouble matching the expected username in
postfwd. Make sure you're using the same name as logged by postfix
smtpd process as sasl_username=
If that doesn't get you going, you can get some rule help from the
postfwd users list. The postfix part is working correctly.

Got it right - thank you Wietse, Noel!
The empty destination like "smtp:" did it, plus I was missing the semicolon after the sasl_username rule part. The semicolon also
made two other rules work ;-) Now all is sweetness and light.
