Yes.

I don't understand this: there is no "outgoing" or "incoming" relaying.
Btw, yes, JAMES Server does support relaying: it can accept messages via
SMTP protocol and deliver them to another SMTP server.

If you need SSL for mail submission then you can configure JAMES Server
to listen to an SSL encrypted port used only for submission.
STARTTLS is not supported by JAMES Server.
I think you can use postfix as you describe: I often did this with
sendmail and it worked fine.

Maybe you want to explain what you mean with "relay": JAMES Server
supports relaying as described in rfc2821.

If you want incoming mail to be processed by postfix simply bind postfix
to port 25 and james server to another port and configure postfix to
relay mail to the james server port (maybe using authentication).

If you want outgoing mail from james server to be sent to your postfix
then configure james RemoteDelivery to use postfix as a gateway.

FWIW ougoing mail for JAMES Server should support STARTTLS. I think this
can be done by using
<mail.smtp.starttls.enable>true</mail.smtp.starttls.enable> in
RemoteDelivery configuration. This way everytime a server announces
STARTTLS support javamail SHOULD (never tried) try to encrypt the
conversation.
