I'm trying to set up Postfix to receive email for a single domain.
Lets call it SCHOOL.COM
and to have the emails delivered to the user depending on which site they are at:
--> Site A
--> Site B
-- Site C
Each site has their own SMTP server.
I do not want to forward emails (as the headers and some times the subject/body changes)
The Postfix server just needs to look up from somewhere where a user is, and then deliver the email to the SMTP server at the site where they work. The destination server can be easily configured to accept email to a correctly addressed recipient.
Many Thanks in advance.
