We do use RBLs in SmarterMail and the header says that:
X-SmarterMail-Spam: Reverse DNS Lookup [Passed], ISpamAssassin 0 [raw: 2], SPF_None, DKIM_None, GBUDB, SORBS-RECENT, Declude: 0
So why does SmarterMail writes this:
X-SmarterMail-TotalSpamWeight: 0
?
What are possible reasons of that? Is there some list like:
1. Trusted sender
2. Whitelisted IP
3. Negative score equal to the positive score
4. ...
5. ...
?
