<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Hello,</div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">
I have AmavisD with the following software running on Gentoo Linux (Kernel Version 3.8.13):</div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default"><ol style><li style><font face="tahoma, sans-serif">Postfix (Version 2.10.)</font></li>
<li style><font face="tahoma, sans-serif">SpamAssassin (Version 3.3.2-r1)</font></li><li style><font face="tahoma, sans-serif">ClamAV (Version 0.97.7)</font></li><li style><font face="tahoma, sans-serif">DCC (Version 1.3.140-r1)</font></li>
<li style><font face="tahoma, sans-serif">Razor (Version 2.85-r1)</font></li></ol><div style><font face="tahoma, sans-serif">There are perhaps quite a few other packages I have installed; I just know these are the major ones I have installed.</font></div>
<div style><font face="tahoma, sans-serif"><br></font></div><div style><font face="tahoma, sans-serif">Anyway, everything works but quite frankly my users still get a significant amount of spam coming through (no viruses whatsoever, so the ClamAV aspect works great.)</font></div>
<div style><font face="tahoma, sans-serif"><br></font></div><div style><font face="tahoma, sans-serif">The core problem is that, from what I see from the logs the score for the spam messages gets rated lower than zero so the system is learning these messages as ham and as such the filter becomes less effective as time goes on.</font></div>
<div style><font face="tahoma, sans-serif"><br></font></div><div style><font face="tahoma, sans-serif">Now, the current install isn't completely ineffective; it catches a great deal of spam messages but my question stems from asking what can I do to greatly increase the accuracy.</font></div>
<div style><font face="tahoma, sans-serif"><br></font></div><div style><font face="tahoma, sans-serif">Is there a guide somewhere on improving detection of spam with AmavisD? I couldn't find such a guide. Much of the items mentioned for improving SpamAssassin was within the "<a href="http://local.cf">local.cf</a>" file but I know AmavisD ignores that (from what I read). I also know I can lower the tag/tag2/etc. numbers but then valid mail gets caught.</font></div>
<div style><font face="tahoma, sans-serif"><br></font></div><div style><font face="tahoma, sans-serif">Any help in this area would be much appreciated.</font></div><div style><font face="tahoma, sans-serif"><br></font></div>
<div style><font face="tahoma, sans-serif">Thank you.<br><br></font></div></div><div>Regards,<br>Christopher Koeber</div>
