Before you do that, I would suggest you read what Henrik K wrote: "There are already major spamtrappers etc contributing to ruleqa, I think most of the "easy dialup" spam is seen there too. Just try to look for the hard to catch spam not ending up in ham corpus." IMO the corpus should contain a bit of everything, but ideally it should be dominated by the spam that would reach SA on a server following best practice. A corpus generated from unfiltered spamtraps is very heavily biased in the wrong direction. Also if someone is processing mail from an MTA they don't control it doesn't mean that there's no upstream MTA filtering. My experience is that lighter (low FP) spam filtering is something you have to pay extra for these days.

I would suggest yes, you should accept everything that reaches your spamtrap addresses and include it in your corpora. Don't worry about that, worry about whether or not the messages get correctly classified. Thanks. I might test next weekend about dropping the postscreen scanning. It has been bearable these days with spam, not a hard labor to work with the ham & spam into dedicated folders. I am subscribed to tons of domestic and foreign ham delivery sources just because of this hobby. -- ja...@iki.fi

Those are both large contributions. Thank you for that support. The obvious repository of things we need fixed is the Bugzilla. There are a lot of open bugs, most of which require some Perl prowess and substantial time to fix, because we've done pretty well on attacking simple bugs as they are reported. There are gaps and flaws in the documentation, both on the Wiki and internal to the code, where many authors have used only standard commenting instead of POD, effectively hiding documentation. rule development is also potentially quite helpful, if you are good at it and have the patience to deal with the testing process (e.g. like John Hardin.) Thank you for your post. I am a professional software developer and work currently as a Senior Java Developer in a large multinational. I know "tons of" programming languages but sadly Perl or Regexp are not part of it. I can READ Perl, but I can not read the Perl book I have to the amount that I could actually be productive in a Perl software project. The language just feels too backwards to me that I can not bother to learn. So I will stick to my day job and ponder other options for this. -- ja...@iki.fi
