Thanks for all
I have read the document
http://www.postfix.org/RESTRICTION_CLASS_README.html
Maybe it's not what I need to setting. I don't have internal email
distribution list, so do not need to protect it. And I don't want to
restrict any user send mail to off-site destinations.
My customer have the mail system, they send mail via my postfix server.
/etc/postfix/main.cf
mynetworks = hash:/etc/postfix/mynetworks_table
/etc/postfix/mynetworks_table
IP PERMIT
IP is my customer's IP, and they have two domain: customer.domain1,
customer.domain2 My mail system only want these two domain send mail via
my postfix mail system but not any other domain. It's mean only two domains
in this IP can send mail via my server, other domains will be reject by my
server
How can I set in main.cf
Thanks for your time
