SPAM filter features

1. White lists
2. Black lists
3. Drop content option for POP and IMAP

Hey Alain,

A blacklist is a great idea.

Each user already has their own whitelist in their quarantine, there is also a global whitelist under quarantine in the main UI.

Unfortunately, we can't implement a drop content option for POP or IMAP because they way the protocol is implemented. The client requests message 5, and we scan message 5 while the client downloads it. If we determine it to be spam, we are still forced to deliver it because the client expects a response to their request. This is also why there isn't a quarantine options for POP or IMAP.
(We've brainstormed about prefetching or caching to get around this, but the implementation looks hard)

Is there any place I can set my own spam score?

Thanks.

Not at this time. You can only adjust the scan strength low, medium, high, very high, and extreme.

Just a thought to the developers. ASSP Anti-spam might be an excellent option to consider as part of the package that Untangle offers. I'm not sure of your licensing/agreements, but ASSP is open source. (assp.sourceforge.net) It's an excellent anti-spam mail system that I've been using for years. Hope you don't consider this spamming. I'm just mentioning it because it already provides all the features under discussion here for email plus many more and is relatively easy to deploy.

Cool! I've never heard about it - I'll check it out. Thanks!

I'll second the ASSP recommendation. We have been using it for two or three years on a couple of sites with about 250 users. It has performed extremely well.

A thrid for the ASSP as well.

Having the other features like your own weighting would be great as well. The system tells you the score the email reached which is good, but that only gets users asking the question about changing that.

Hi everybody!

I would like to consider the fact that , at the moment, it could be a higher jump to the edge, "a bonus" if we could integrate the DSPAM(www.nuclearelephant.com) anti-spam module right beside ASSP, into untangle SPAM prevention method.

"DSPAM's author claims that typical users of DSPAM have reported from 99.5 to 99.95% accuracy, including "best recorded levels of accuracy ... 99.991% by one avid user (2 errors in 22,786) and 99.987% by the author.
The project consists of a library, libdspam, which contains the core filtering and storage routines, and command-line and web-based interfaces. DSPAM is MTA-independent, can store spam classification data in a number of database formats, and uses bayesian filtering to learn and adapt to spam."

Any user ,or forum reader, who used DSPAM+ASSP?

THANX!

Are there any spamassassin plugins for DSPAM and ASSP?
