configure postfix to send as different domains
- by Cerales
I have postfix configured to receive mail for multiple domains. The primary domain goes through a standard postfix setup, whereas a secondary domain is handed by a /etc/postfix/virtual.db file which maps addresses for the secondary domain to other unix users.
Incoming mail works perfectly, but when I send mail as users on the secondary domain, the mail receiver still sees it as coming from [unix username]@[primarydomain].net. Can anyone help me figure out how to configure the virtual postfix domain to send mail through the same domain it receives it as?
