Config of DNS and Mail Server for using mail gateway
Hi, maybe the following question can be a little n00b but is causing me some confusion.
We have at work a Scalix Mail server, running by its own for corporate mails of my domain. I wanted to have a Mail antispam gateway for handling these kind of junk mail. I followed the SpamSnake How to (for ubuntu 11.10), and changed the sendmail.mc SMARTHOST configuration to use the gateway, but now, all the outgoing mails are filtered by the gateway, but none of the incoming ones. I suspect i have to change the MX record on the DNS to make my spamsnake the first mailserver for the domain.
I hope i'm being clear.
Thanks for any help!
