 Topic: No text in message bodyPosted: 24 July 2003 at 6:38pm |

I'm wondering how can we block those emails that don't actually have any text in the message body (they may only have a html picture but the subject may have text) Such an example please see the following: Message subject: the amazing chillow comfort system There is no text in message body but a linked picture, if you look at the source: <html><body><div align="center"> Can we have a RegEx to block this kind of spam? Thanks |

Danny, You won't like my answer .... I don't like it either! I can very easily block it but it will block TONS of valid email. The only recorse is to do what I do ... I run my own dnsbl list and once a day, I parse my mail logs against IP's that messages like these come in from. If I find more than 10 on the single IP, I add it to the dns server. If I find more than 25 from the same clacc C, I block the whole C block. I the submit the message to njabl as a spam and see if they block it. Dan S.

Frank, A dnsbl is simply a DNS server configured with the proper blackhole zones. I am using Windows 2000's DNS server. Dan |

I know, thought you are maybe using a special Software like this one: http://cr.yp.to/djbdns/rbldns.html - or one with some special features.
I am still looking for a Windows based local blacklist system, able to handle automatic input via spamtraps and manual submissions. Frank
