host means host - quite simple.

From: 	host:mail.example.com	yes

reads like this :

If a mail comes from host mail.example.com (no matter what sender domain 
is used) then hand over "yes" to the related variable.


From: 	mail.example.com	yes
From: 	*@mail.example.com	yes

read the same

If a mail comes from domain mail.example.com then hand over "yes"

From: 	*@example.com	yes

this handles only mails from example.com, the mail.example.com domain 
has to be handeled separately

From: 	*@*.example.com	yes

and this handles mails from any subdomain of example.com but not 
directly from example.com


From: 	*@*example.com	yes

this handles mails from example.com and its subdomains but also from 
anyexample.com, myexample.com, dumbexample.com ......
