Yes, I have seen similar e-mails and yes, this appears to be word list probes to see what will and will not pass through your filter. Once they compile a reasonable trigger list, they will omit those words from their SPAM messages. This also explains why the e-mail is coming from random sources. If it came from a real address, they know that any reasonable admin would add the domain to their block list.

Hi, Perhaps some spammers trying to test circumvention of anti-spam filter ? Just filling mail with random words to test if this can pass some score-based filter like Baysian filter? If those messages are accepted, they will try later with some advertising for a Miracle Pill to make some part of your body bigger ? ;-) Regards, Max -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: mardi 30 d�cembre 2003 13:48 To: [EMAIL PROTECTED] Subject: [Full-Disclosure] weird worm ?
