Any luck with tmda?

[DrkShdw]

Hi guys,

I've been using the mail toaster for quite a while.  However,  I have a standard qmail setup on a private server that I have only been using for personal domains.   within the last two years,  I've noticed a HUGE increase in spam to the domains..  and did some research.   I found tmda (http://www.tmda.net" target="_blank">http://www.tmda.net) and have had incredible results with it.

Now,   I'm tempted to install it on my mail toaster setup,  but I was wondering if anyone has had any success with such a configuration?  It seems like a great anti-spam feature with the challenge/response and whitelisting.. (making me wonder why it isn't already an option in the toaster)

At first,  I'd only like to tmda some test addresses,  then migrate to just doing it for my personal email accounts.

If it works well,  I'd like to write a web frontend to enable/disable tmda on a per-user account basis.

So:  advice?   has anyone made a go of it?
