Hello,
We have a 'challenge' to make something work. I hope someone can guide
me in the right direction. The following has to take place :
We have a postfix mailserver which uses relay and virtual files for
incoming and outgoing E-Mail traffic. We must be able to accept a new
incoming relay from google-apps for an address rewrite and outgoing. But
we want to make sure the incoming E-Mail from google-apps is from
google, so we want to make some restrictions :
1. The incoming relay is from Google (IP address check)
2. From address is : ***@google1.com (example)
3. Custom X header in the E-Mail.
How can we fit this into our config ? I am looking at custom header
checks for the X Header, but I want to make this ONE access rule, not
three seperate on different places so the incoming E-Mail has to conform
to this rule.
Greetings, Richard Smits.
