Dear Pros'
I am facing a problem in getting system generated mails to my local mailbox.
let me explain the scenario.
Postfix Mail Server <---> Firewall <---> External Mail Hosting
example.com external.com
To our internal Postfix Mail Server, we are receiving mails from outside
through a third party service provider. Fetchmail is downloading from postfix
to get mails from the external mail server.
Now we have our example.com domain internal details explained in an Internal
DNS Server, with the MX entry pointing to the internal Postfix Mail Server.
Our example.com domain is registered (internal and external domain are same)
and it have its own MX record in the internet which points to our external
hosting's mail server.
In our firewall, the DNS is pointed to external DNS servers, as usual. Now when
the firewall is trying to send system related messaged to my local account, it
is sending to the External Mail Server (bcoz of the MX entry from the external
DNS) and this mail is rejected because, the from address is not able to verify
by the external Mail Server ( from address from logwatch event is like
logwa...@example.com)
Now i want my firewall to send mail to our internal POSTFIX mail server. How
can i achieve that WITHOUT changing the dns servers to internal (it shoud be
external in the firewall).
So i feel like, if we can locally set MX which points to Internal Postfix Mail
Server in the firewall, that will do the trick...
but i dont know whether it is possible or how to do that???
