postfix multiple domains send emails only
I am setting up a Postfix MTA that will be only sending mail for different virtual domains. We have other servers that will be receiving the mail for the domains so I only need to set up for sending on Postfix. What my issue is I am trying to configure Postfix so that when it sends mail the header shows what domain the mail came from and not the domain the Postfix server is set to. For example.... Postfix server domain: domain1.com Mail domain: domain2.com Mail domain: domain3.com When I send mail from domain2.com I want it to show in the header it was sent from domain2.com and not from domain1.com. What do I need to set in postfix so that this happens? Right now no matter what domain the mail is from the header always shows the server domain and I can't have that. Any help is greatly appreciated.
