yes if you have an "internal side". do you?   

I have 3+ sides. External, wired and wireless. I may eventually add a dmz or include the dmz with wireless. Wired and wireless both go through the server to external but don't know the other exists.

putting the internal on different ports is not a problem if you cant specify different settings for the different sides of the server specifically.
the way the documentation is worded it confuses me which one would apply
here. does smtpd_sender... = out going mail or the from: box?
the way you word it confuses me:)

Havent studied much on mail servers before. until a year or 2 agao my systems hadent seen much spam. Some one used my domain in the from box for a bunch of spam and now i get alot of junk.

No, this won't work, rather:

     smtpd_recipient_restrictions =
        permit_sasl_authenticated,
        permit_mynetworks,
        reject_unauth_destination,
        check_sender_access hash:/etc/postfix/access_sender
        # Optional final permit, just to make it clear
        permit

Does that apply to multi homed machines or is it possible to specify things per network? or would i be better off having a mail server instance specifically for external mail and a 2nd server that is for the internal clients?
