It was around three weeks ago that I completely implemented the MailToaster into SimpleApps and started using this configuration for my own personal email.
I use to wake up to about 50 spam message every morning, now it is down to about 10. That may not sound like the results that one might expect, but I had spent a good deal of time working on my own filters and using RBLs.
So this is proof to me that the MailToaster really does what it says and is a great email server for just about anywhere.
