Certian Type of Spam just wont get filtered! RSS Back to forum


I am having an issue with a certian type of spam that keeps bypassing ORF, we ahve the latest version and this type spam basically shows a large image in teh body and changes teh subject line so you cant keyword blacklist. I have also notice that it will change it domain name everyday as well to get past I will copy and paste just a few different domain names that it comes from so I cant blacklist it because it changes way to often. I have turned on SPF and RDNS on (both:before and after arrival) and it still doesnt catch it. Here is a few domain names that it comes from like I said it always changes:

pharmacy assistant programs []
physicians blend hgh spray []
accounting degrees []

It is very annoying one user gets about 50 of these a day, any ideas or anyone need more information?

@Grant: Are you using DNSBL's and SURBL's? I use Barracuda, spamhaus zen, spamcop, and combined surbl lists and haven't had a problem with these.

I suggest you add the combined surbl list located in configuration/filtering/on arrival/url blacklists and see if that helps. It filters urls in messages that could lead to images.
