I will try to explain better what is my problem. In our structure we have "some" mail servers (for security reasons we have a complete separate structure between internal and external network, when we receive a mail from Internet we must use a terminal server to access the external mail server): - An internal Exchange - An external Exchenge - An external appliance as a Mail relay for normal users mail traffic - An external appliance as a Mail relay for batch/automatic mail traffic Usually when an "internal" server needs to send mails on internet we used to open the port 25 on the firewall to permit that server to access the "external batch mail relay". Now we'd like to implement an internal mail relay which will do the job of send internet mail (through the ""external batch mail relay") for the internal servers that need this. The problem is that this mail relay (postfix) should filter who and where can send the mails; something like: Group of internal servers (SMTP clients) - Recipients permitted client1,client4,client7 - us...@domain1.com, <mailto:us...@domain1.com,us...@domain2.com> us...@domain2.com client2,client3,client4 - us...@domain6.com, <mailto:us...@domain6.com,> us...@domain4.com <mailto:us...@domain4.com> with Regards, Daniel ________________________________

Please describe the *problem* that you want to solve, instead of
the solution (rules/routing).
