Hi!,
I've seen a lot of this questions here. None of the answers had
helped me. So, here is my problem,
I'm using my postfix box to relay to a exchange server, everything
works ok until someone tries to send mail from outside my network to
other than $mydomain. If the users sends the mail from my internal
network, the mail goes ok to the external domain.
If I put the IP address of the external network where the user sends
the email in $mynetworks, everything works ok, but since I don't know
all the ip addresses where my users will send mail from this is not a
valid solution
