Hello, My friend This is Tom, I'm sending my greeting from China I Use postfix for few month, My customer send mail via my mail server, So, some IP is in mynetworks setting. for example, my_customer_server_ip is permit send mail via my server But there is something serious with my postfix server
The correct log is just like that May 30 08:09:01 [my_customer_server_ip] [my_customer_client_ip] <user@mycustomer.domain> -> <some...@example.com>, The wrong log is just like that,(hotmail.com, yahoo.com is the example) May 29 18:05:35 , [my_customer_server_ip] [other_ip] <any...@hotmail.com> -> <some...@example.com>, May 29 16:05:37 , [my_customer_server_ip] [other_ip] <any...@yahoo.com> -> < some...@example.com>, any...@hotmail.com, any...@yahoo.com, etc. maybe real address in the internet mail system, but it's not a real mail account in my customer's mail system. My purpose is permit my_customer_ip send mail via my mail server, only permit my customer domain address send mail, reject any other domain send mail via my_customer_ip, how can I setting in my postfix. Thanks a lot Tom
