What I have/had now was the following:
master.cf:
192.168.0.11:smtp inet n - - - -
smtpd
-o relayhost=[192.168.0.10]:225
192.168.0.11:125 inet n - - - -
smtpd
-o relayhost=
The intent was to have local clients connect to 192.168.0.11:25.
Postfix should then relay it to 192.168.0.10:225. That relay will
then process and return it to 192.168.0.11:125 - which would then
send it to the destination.
Right now, the above config "functions" in that it receives a message
from a client and delivers it to the destination - but it never hits
my filter.
No, because smtpd(8) doesn't pay attention to the relayhost parameter
and doesn't pass it on to the rest of Postfix. Postfix is modular, and
the relayhost is not a per-message property.
You're on the right track, just use content_filter instead. See
FILTER_README.
I'm closing in on it - now for some fine-tuning. Now, a test master.cf
contains:
192.168.0.11:smtp inet n - - - - smtpd
-o smtpd_proxy_filter=inet:192.168.0.11:325
192.168.0.11:325 inet n - - - - smtpd
-o smtpd_proxy_filter=
This actually works - I can see in the log the relay between the
processes and then the handoff to the remote server.

Now - to see what's broken. When the smtpd_proxy_filter line is pointed
to the real proxy, and the proxy is pointed to return to the :325 port,
my log shows:

Does this indicate a Postfix problem? Or is my proxy filter mangling
something?
Looks as if the proxy filter has gotten out of sync with postfix.
I would suggest starting using it as a content_filter. Once
you get that working, you can see if it works with
smtpd_proxy_filter.
I find it handy to use " -o syslog_name=postfix-something" in
master.cf to differentiate services; makes reading the logs
easier.
