As I already noted in this thread, doing this on a single machines is
typically best accomplished via a MULTI-INSTANCE configuration, with

I read over multi instance and it feels heavy handed / overkill for what
im trying to accomplish considering changing transport from virtual to
smtp: accomplishes my goal. The only issue is it seems i can not get
postfix to use virtual by default and smtp: for submission. I know you
pointed me at multi instance but you didn't explicitly say postfix can
not change the value of transport under submission -o options. Can this
be done?
Forwarding from submission to port 25 on the same machine generally
runs
into loop detection issues. However, you may be able to avoid this by
setting the port 25 MTA as a proxy filter via:
I do not understand how what im asking would cause a loop issue. If mail
received by submission service uses transport smtp: which then connects
to smtp:25 and smtpd service by default uses transport=virtual it would
never loop. Unless again the answer is postfix isn't designed to change
the value of -o transport in master.cf?
