[HCoop-Discuss] RFC-Ignorant and SpamAssassin

[Franklin Gordon Bynum]

Recently here we've discussed the increase in false positives showing  
up in our Spam folders.  My increase has been fairly dramatic in the  
past two weeks.  I've been feeding the shared folders, as always, but  
more and more personal messages sent from reputable ISPs (mostly  
Yahoo) are being blocked.

I've analyzed the messages and found that the tags that almost always  
wrongly kick messages over the 5.0 points mark are the "rfc-ignorant"  
tags.  For those who aren't familiar with them, they are tags that  
poll this "blacklist" of domains that don't maintain servers  
complaint with certain RFCs, namely those directing to have an  
abuse at domain account and a postmaster at doman account.

I find this database to do more harm than good, and would like some  
of you to take a look at your false positives to see if you agree.   
For example, all messages form Yahoo accounts-- the world's most  
popular webmail system-- start right out of the gate with 3.5 points,  
just a few key words or a missing real name away from going straight  
to the spam folder.  I think that's unacceptable.  (Now, indeed it is  
also unacceptable for Yahoo to not play nicely and I've submitted a  
support ticket as surely many others have.)

Could we at least reduce the score for these lists?  Especially the  
postmaster score that's outright excessive at 1.7.

I'll figure out how if people are interested in improving our spam  
filter.  I sure am.
