I got the postfix->courier-imap set up on the new server (which I creatively called [b]fritz[/b]). Since I had already previously gotten the virtual user setup working on the old server, this was way easier. Now, I'm moving on to enabling dspam - which is going to be the most complex part of the whole adventure, mainly because I don't understand dspam very well. I don't know how aliases will work - and that a big part of the the training thing. So, tommorrow - while I'm watching football, I'm going to install dspam, train it with ham and spam, and see if I can get it reliably working.
