Just to further illustrate my point, here's the score header from a very obvious spam mail:
I realize DSPAM doesn't check blacklists, but in spite of SA's Bayesian filter being 99% sure it was spam, DSPAM still thinks it's innocent - thankfully it still made it to junk due to SA scoring it so high. I randomly checked about 20 really obvious junk emails and DSPAM had marked them all as innocent. To date, I've not actually been able to find an email that DSPAM flagged correctly.

Here's a header from my Xbox newsletter, which gets stuck in Junk thanks to DSPAM:
This a valid-format newsletter that I subscribe to that scored into the negative with SA, but... here comes SA's retarted cousin DSPAM junking it for me.

This program is completely asinine.
