Hi Mark,

Thanks so much for the link. Getting a better understanding of Sieve was on my to-do list. This gives me a great concrete project for my first foray. 🙂

I was hoping there was just a switch I could throw in Dovecot to route the message, but I guess this is a living example of the modularity in modern open-source software. 🙂

Thanks,

Scott

You probably need to take advantage of sieve scripts so here is a super
lightweight spam filtering system that might provide some useful clues..
