host parm

[Steve Campbell]

I seem to recall something about using the parameter "host" in one or 
some of the rules/conf files. Can someone refresh my memory on how/where 
that's used and what version did it become available?

I'm getting a ton of emails from one of those hosting domains, and 
although I could block the entire class C in my access file, some of the 
individual IPs are not necessarily bad and and the envelop doesn't 
contain the domain name of the hosting class c.

So, if I could put something in a file like "host:   softlayer.com" or 
something like that, it'd be great as the IPs resolve to this domain, 
but might actually show a differing domain name in the envelop.

Thanks for any help.
