Redirecting all emails from a server to a mail list in Exchange
From MyWiki
Two test servers 10.0.0.25 and 10.0.0.26 send emails out, which need to be re-directed to a mail distribution list in MS Exchange. Developers are members of the distribution list and that way they get all emails that may come out of the two servers.
So, I added the below to main.cf on Postfix SMTP gateway that the two servers send emails through:
smtpd_client_restrictions = check_client_access hash:/etc/postfix/client_access
In the /etc/postfix/client_access file I have:
10.0.0.25 REDIRECT test@company.com 10.0.0.26 REDIRECT test@company.com
Create the map:
# postmap hash:/etc/postfix/client_access
Reload postfix configuration and enjoy emails re-directed to test@company.com
