That depends on how you see it. If you are thinking about the spam ratio, yes, you are correct. RBLs can filter up to 90% of all the spam (in my experience). On the other hand, if you are being targeted by 1000's of spams daily, you will still get a fair number of them. > I would suggest otherwise.

As I stated before, one of the best things about maildir is that you can use incremental backup procedures. So I second that idea, no matter if you are keeping the maildirs on /home or /var/spool/mail. > Yes.

Is it really recomended (cost/benefit) to mix two different MTA's ? I never tried that. I just start on the idea that it would simply add too much complexity. Then again, I might be misinformed, and the benefits be enough to make it worth. Care you elaborate a little more on that one, please ?
