My managment has recently asked me how SpamAssassin is prepared to deal with a number of recent trends in spam technology. This was prompted by a recent seminar they attended regarding spam (provided by an anti-spam vendor who shall remain nameless).
None of these so-called recent spam trends are new to me or probably to anyone who deals with spam on a daily basis. However, while drafting my reply I had the thought that perhaps my answers would carry more weight if I could include some quotes from other people in the industry regarding SA's ability to handle spam utilizing these techniques. I've done some cursory browsing through the list archives but thought I might solicit some fresh input from the list-members.
These are the recent trends raised by my management:
Hash Busting - slightly modify each copy of message to foil 'fingerprinting' techniques
Bayes Poisoning - addition of random dictionary words
Hidden Text - using invisible text in html messages
Keyword Corruption - using obfuscated text to hide keywords
Tiny Messages - messages with only URL or image
I'd appreciate any comments on how SA handles these types of spamming nastiness.
Thanks,
