For the last few days, I've been fiddling with my new postfix installation (which has been working quite well), trying to figure out how to even out my current 200 to 1 spam ratio.
I'm now trying out dspam, and I have all the routing working, and the web interface is working (finally), but the only problem I'm having is, well... All the training I'm doing seems to be failing miserably. I'll keep at it, because in my opinion, it's still far too early to hope for good results.
Anyway.. I followed
this tutorial, which seemed very well done. Just thought I'd share.
Also, as far as sasl authentication goes, I found
this tutorial quite helpful, as well.
