Hi,
This would generate high volume of false/positives. Regular mails can also contain inline images, this is often used.

since nearly 99% of spam attaches an inline gif, what about writing a rule to mark it as spam? Bill Adam Campbell wrote: Add the sender's IP to a custom DNSBL. Tell antispamseeder it's a spam message. Do you check for valid helo? For valid reverse dns? For valid from? I use only IMail for spam-filtering. Any message that fails a test (except valhelo - happens too much on good messages) is diverted. Any message that is diverted in a user's mailbox is also diverted in the archive mailbox. I regularly check the archive mailbox for any good messages. Any good messages diverted I revert/restore in the user's mailbox. I'm looking into a better solution. adamc Martin Schaible wrote: Hi, We analyzed the mail too and we couldn't find any phrase or html construct to create a rule. I'm alos wondering how other spam filters are dealing with mails like this. ============================================ Am Montag, 27.

The trouble is that mortality sometimes comes to him so suddenly! And he cannot even say what he will be doing this evening.' 'What a stupid way of putting the question. ' thought Berlioz and objected : 'Now there you exaggerate. I know more or less exactly what I'm going to be doing this evening. Provided of course that a brick doesn't fall on my head in the street. . .' 'A brick is neither here nor there,' the stranger interrupted persuasively. ' A brick never falls on anyone's head. You in particular, I assure you, are in no danger from that. Your death will be different.' 'Perhaps you know exactly how I am going to die? ' enquired Berlioz with understandable sarcasm at the ridiculous turn that the conversation seemed to be taking. ' Would you like to tell me?' 'Certainly,' rejoined the stranger.
