How to setup the mail server (by using sendmail) with basic spam mail protection. At least enable the sender DNS reverse lookup feature.

The mail server is running Linux. Please help! Thks.

I can't help with Linux, but I do remember someone here disagreeing with me, when I said Linux is not widely used, they said yes, it was, I said no, not from the many people I run into.

So if they are correct, you should hopefully have no problem finding the help on this one that you need.

Sorry I could not. :confused:
