You can have both too: SpamAssassin and blacklisting. Exim4 can pass the mail to SA while keeping the SMTP connection open. That way I can decide based on several BLs and further tests if I want to reject or accept the message. My user can even decide on their own if mail is ever rejected, and if yes how many SA points are required. Works very well. Thomas
