I have the same issue as I'm sure many people do who have private
domains behind a NAT server connected to their ISP. I would like to
masquerade my sender address based on where the mail is going. If it is
being sent locally -> don't masquerade; if it is to be forwarded to my
ISP -> change the sender address to my email address at the ISP.
I went through the Postfix website and could not find anything other
than simple masquerading. For example, if you want to masquerade, all
sender addresses are masqueraded. I don't see control structure
mechanisms (if/else) like Sendmail has. Even with Sendmail, I think
I'll have to edit the .cf file directly. Maybe someone on the SLUG list
has already done this with Postfix, Sendmail, QMail.... This seems like
it should have a quick fix, maybe even a one-liner.
