how to get a decent postfix spamassassin setup?

[sepp]

Hi,I've been playing with amavisd-new and spamassassin the last days. but it seems as amavisd-new cuts down the features spamassassin brings along. Also the sql settings feature doesn't seem to work that well. SoI'm curious and would like to know how you guys have setup up postfix to work along with spamassassin. I've seen solution with passing mail from postfix to procmail and then to spamassassin. but this seems to me to be not very efficient (correct me if I'm wrong). So if you know a flexible and scalable postfix+spamassassin solution that can even handle user settings from sql, please share with me. The best would be to also deliver spam mails to a courier imap spam mailbox.
