Best practices...

Block if...

1) IPrev lookups fail.

2) SPF lookup fails.

3) DKIM lookup fails or DKIM signature check fails.

4) Block by Geo if all else fails.

For example, currently I'm getting massive SPAM from a .ru domain which has #1-#3 all configured correctly.

To me, this makes no sense + it is as it is...

So when this occurs, you can block all mail from one sending domain/host or the entire Geo.

Since I don't work with any Russian companies currently, I can just block the entire Geo.
