Dear community, I'm trying to learn how to set a server using Postfix, this is a very complex craft and I can't grasp yet the full potential of this tool. I would need to know if it can do these actions : John Doe has a gmail address : [email protected], and a mydomain address : [email protected] Jane Smith has a gmail address: [email protected], and a mydomain address : [email protected] The process I need to do is : [email protected] sends an email to [email protected] The MTA filters the sender address : john.doe has a mydomain address = ok And the sender's recipient : john.doe is allowed to email [email protected] (meaning John Doe can't email all the mydomain addresses, some are restricted for him) = ok = my MTA accept the email (Rewritting) The sender is changed (envelop and header) for [email protected] (Rewritting) The recipient is changed for [email protected] [email protected] receives a message from [email protected] Can I set up such a complex process with Postfix or Exim (or another MTA ?) ? Thank you very much for your help and expertise !
Short answer is: yes of course you can do that with postfix ( not sure about exim ). But it may be some additional work - ISPConfig doesn't have such a feature out of the box afaik. Maybe this link will help you http://www.postfix.org/access.5.html
