I just moved SA outside the firewall. Spam filtering is working much better, but I'm not sure how to proceed on feeding missed spam back into bayes. By the time it gets to my mailbox, it's gone through the firewall, the virus scanner, and the email server; each leaving a large or small fingerprint on the email. Any recommendations on how to start populating a new bayes db with this setup? I'm assuming I don't want to use the email in my mailbox, as it's been tainted by the intermediate in-house stops.
Details: Internet -> outside box (containing greylist, SA, pyzor, and dcc) -> firewall -> virus scanner -> email server -> mailbox SA 3.04 Thanks
