[Mimedefang] Integrating SPF...

[John Von Essen]

David,

So its not in MD 2.51, but it is in CanIt, right?

How would MD handle it though? Does it effect spam score, or is it used as
a blind rule?

Correct me if I am wrong, but the spf record will return a few possible
results. Fail, Softfail, pass, neutral. If it returns Fail, I am confident
enough to simply drop the email entirely at the MD layer.

>From what I have found, very few people use fail (-all), rather they use
softfail (~all).

If thats the case, then in MD I guess you would do something like:

1. Drop it if it returns fail.
2. If it returns softfail proceed, then add 3.0 to spame score, etc.,.

Of course, if SA has the spf rule, then you would just need (1).

If you are going to implement something like this in a MD release, thats
great. Otherwise I'll just use SpamAssassin's rule for now.

Thanks
John
