Looking through my caught spam folder I found at least one case where a base64-encoded message body was scanned for keywords. Here are some of the results:
SPAM: Content analysis details: (13.70 hits, 5 required) ... SPAM: NASTY_GIRLS (2.2 points) BODY: Possible porn - Nasty Girls ... SPAM: BASE64_ENC_TEXT (1.4 points) RAW: Message text disguised using base-64 encoding I am running SpamAssassin 2.44, so I know that some released versions of SpamAssassin can scan encoded content. The message body in this case also had the type set to text/plain, so maybe the messages that are getting through your filters are obfuscated in some other way. -- Matt Wronkiewicz <[EMAIL PROTECTED]> Fingerprint: 914B FFE7 1C00 7B63 04D1 051D BA18 9B5D 6845 2D6E Signature policy: http://www.foozone.org/crypto_policy.asc
