You could create a filter that looks for these types of links. If there is NOT a http://x.x.x.x regular expression then it would most likely be spam.
FWIW, here's how you create them: To convert an IP to integer: Note that the % is the standard C arithmetic operator ((2^24)*A)+((2^16)*B)+((2^8)*C)+D = integer value of an IP address Where A, B, C, D are the individual octets in the IP address: A.B.C.D To convert the Integer to IP: Take the integer value of the number divided by 16777216 (2^24) that's the first octet. Octet 1 = int(number / 16777216) or int(100000000/162777216) = 5 Take the integer value of the number divided by 65536 (2^16) that's the second octet. Octet 2 = int(number / 65536) or int(100000000/65536) = 245 Take the integer value of the number divided by 256 (2^8) that's the third octet. Octet 3 = int(number / 256) or int(100000000/256) = 225 Take the integer value of the number % 256 that's the fourth octet. Octet 4 = number % 256 or 100000000 % 256 = 0 5.245.225.0 Mark > Also what we are finding is they are turning the links and > addresses into binary numbers, therefore making it impossible > to detect the links and trap them...

Regards, Kami -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Rick Davidson Sent: Wednesday, September 04, 2002 4:43 PM To: [EMAIL PROTECTED] Subject: [Declude.JunkMail] Encoded Email... how? Howdy, This one has me baffled. This email (spam) showed up as what appeared to be an html formatted message. When I view the raw message it appears as an encoded attachment making it impossible to filter on any body content. How are they doing it and how do we stop it? Have a great day!
