<TITLE>RE: Pyzor and Razor and DCC</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>I've recently added Razor and DCC and modified my reporting to track their usage.</FONT>
</P>
<P><FONT SIZE=2>We currently receive approx 6000 emails a day from the internet and somewhere between 30-40% are considered spam, sometimes it's as high as 60%.</FONT></P>
<P><FONT SIZE=2>From skimming my reports for the last week, approx. 1500-2000 messages are identified as spam by DCC and about 200-300 by Razor.</FONT></P>
<P><FONT SIZE=2>I also track where DCC or Razor made a difference between the mail being considered spam or not. Only about 50-100 messages are considered spam because of DCC or Razor. This is with Required SpamAssassin Score = 5.</FONT></P>
<P><FONT SIZE=2>For me adding Razor and DCC has raised scores and is probably going to make it more likely for me to add delete to my High Scoring Spam Actions but doesn't really make a huge difference to the number of emails considered spam.</FONT></P>
<P><FONT SIZE=2>Of course, this all depends on your scoring for DCC and Razor, mine are at defaults right now.</FONT>
</P>
<P><FONT SIZE=2>I may consider raising the score for DCC, but does this mean more false positives due to mailing lists?</FONT>
</P>
<P><FONT SIZE=2>The other thing I'm considering is turning them off since they don't seem to make much of a difference and are prime suspects when mail starts queuing.</FONT></P>
<P><FONT SIZE=2>My 2 cents.</FONT>

<P><FONT SIZE=2>I'm currently running Razor and am very happy with the results so far. The</FONT>
<BR><FONT SIZE=2>server gets a little behind on occasion, but it always catches up quickly.</FONT>
<BR><FONT SIZE=2>My question is this: What is the advantage - in terms of spam catching</FONT>
<BR><FONT SIZE=2>ability - to using Pyzor and DCC? Are we talking a 10% improvement, 50%,</FONT>
<BR><FONT SIZE=2>200%, what?</FONT>
</P>
<P><FONT SIZE=2>TIA,</FONT>
