In your example text from the zimbraMtaRestrictions the DNS Checks are listed (reject_unknown_client, etc). But in the paragraph you show listing the command to enable RBL feature you don't include the DNS Checks.

Is that an oversight in the details? Or is that because they're a bit obscure, and not common practice to set? IE, you'll get rejections from... who... netadmins who don't set up reverse dns?

I've been reviewing the forum trying to find mention of problems when these are set, but few show examples that they've set them, and no one mentions the DNS Checks are giving them problems.

So what is best practice for these three settings? Yes, no, some, YMMV?

Cheers,
