This this is the best place to post this, I am about to switch to the new 2013 NIS and I was wondoring if it was possible to block ip addresses to filter out the spam (been getting a lot of new spam which has been going around the Norton Antispam).
NIS blocks names but not IP addresses. Are you using an email client [outlook, thunderbird] or a web based service [gmail, etc.]?
I use the filter on the web based service to screen out most of the trash and the filter in outlook to do the rest of the job. That leaves NIS with those pieces of spam and other unusual trash to trap and dump. So far the system seems to be working well.
thanks for the input but I thought that an IP block would look for the IP address in the source code? It provides a series of IP numbers coming from the source of the e-mail through to the ISP.
In any case the spam seems to be completely random from location to e-mail domains, the best I can do is a series of rules based on the vulgar meanings in the message body, for a time however most of them came from Southern US and Russia.
Norton does its best to screen any spam but this is really difficult to get its head around how to block these new ones.
Also I use Outlook and the e-mail I use is not a free one, it comes with my ISP.
