I'm quite happy with dspam - it catches the majority of my spam and I haven't had any false positives since I reinstalled it a few months ago.

I probably didn't explain myself very well - it's not spam bounces that I want to stop. What currently happens is that sendmail accepts a message with NULLs in, passes it to dspam which then passes it to Cyrus. Cyrus then rejects it and causes sendmail to generate a bounce message. Unfortunately, most of these message rejected by cyrus bounce messages seem to be in response to spam (but not always) and hence to non-existant addresses. It then sits in the mail queue for days before making sendmail panic and drop it. I'm happy for the message to be accepted by cyrus and then, if it is spam, for dspam to be retrained to quarantine such messages. > I had to "debug" once delivery from my site to site implementing policy > of dev nulling messages *classified* as spam.

However, I'm definitely going to install the Clam AV milter and possibly the grey listing one too! :-) Take care, Ben -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iQIVAwUBQ9JQrOgNmph0Y1E2AQJSvg//bW6ltbGwlEMRJKu6XosOuYnX7zcUg2zk etnggjrzOmJnRIzggBwDlEyeLJXdBUmx53j2oQIRvA/hI5/NZy22pRD5jhkZlrZe mBvJwD7YhRz1qJU2bLekDt+yjPrf//HBES/6ZB+lXvArm8Nxc024oH/70uwGhnw1 MqL8HiHdPIZnZUaWY8XRLrDT4mNpO9JWupbmrulK6K7XrHXo94UPhiu/4DBxwm8o h2+St0mmhoPi2YeQE8cH3HuJk1ZhHzCN4y4KKa/BR1zstxdSS3va42iXsJvlQSSy jEq9voS12tF3tEoq3iFKLAKdD7D6LbwrpWg41UhPPBWfQnaX43O9ScAu/0mI5vSq l+YOIXqk5C14NA74hceUJaiBgZwxuDr2jkGNnbVx7Ko4cWcYn2MTkS1u5d2QVi6b mulqFwp1SrSlvWjNySicUJqUArpli8hLVYhiGefz7fd5imYQeCShEs047zLOBQhS gCP5/8LftXtMu2f25wAZMAza6OLA+cCNCE0ZLBSc/lKY7GWmiCnCt0ktAXT1PCmj BqkbLESMDMgfUM9BGTO6sMdBBB9JF5gidJsY5wqk8/Xue96GI/8gx6+rhKkLolZ6 u7h3ApGlAXOTP0eklvosDhAkfzYOXggPff44BaYAeFXAyrnuqCiQx3yWDd2pMGo0 /xG2gF2FT6U= =fyRU -----END PGP SIGNATURE----- ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
