SPF does help in scoring spam, I use it myself and it works alongside other anti spam measures just fine.
I'm not sure why you are talking about DHCP addresses as these are only used on an internal network and not across the internet. DHCP addresses are issued on request from an address pool by a DHCP server, typically on the Class A, B, C reserved IP ranges (10.x.x.x, 172.16.x.x and 192.168.1.x). They are also used by ISP's for client connections. In situations where your IP address will vary because you are getting it from a DHCP pool then it's impossible to do any authentication against the IP address unless you allow/block the whole DHCP range. You can, on some mail servers, use SMTP authentication to bypass all other verification of the email sending server/client.

OK, so seems SPF isnt going to get me anything. What about adding the dul blacklist from sorbs? I'm trying to stop viruses, and it seems they all come from DHCP addresses. If I added the DHCP address to my spam filter, wouldnt i be able to block those? Also, if I do that, will I still be able to send from my DHCP address if I use SMTP Auth? (i.e. does that bypass the filter)? -Dov ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:228763 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
