Gentoo has quite a large list of apps in their mail-filter category.  I  
have started to go through them, but so far, the problem for me is that  
most of the are not suitable for my usage - a single user wanting to  
filter multiple pop3 feeds.  When I have more time, I'll go through the  
list with a bit more care than I have bothered with so far.  However,  
thanks for the suggestions.
