to edit slightly. You specify your Exchange server, and it will query
it. The conf file is also where you can white/blacklist specific
addresses, domains, etc. It is fairly efficient, as it caches the results
so that it's not asking the Exchange server about every message. I think
the TTL is 3 hours, but it can be changed as well.</FONT></SPAN></DIV>

sorry for bothering you, but is there a description on how smf-sav actually
works. How does it check the recipient of my domains? Does it know somehow
how to get to the exchange server for each domain>? I cant find any

<P class=MsoNormal>you need to do a lookup on each address rather than keeping
it a file you have to maintain - smf-sav can do this quite easily although it's
main purpose it to check senders it can also check
recipients <o:p></o:p></P></DIV>

<P><SPAN lang=EN-GB>Hi All,</SPAN><o:p></o:p></P>
<P><SPAN lang=EN-GB> </SPAN><o:p></o:p></P>
<P><SPAN lang=EN-GB>Recently I am finding that the amount of incoming mail
through my MailScanner Server is really slowing down things. There
is a heavy load now since I took on a domain that seems to me well spammed.
Yesterdays processing processed 22,000 emails @88% Spam
approx.</SPAN><o:p></o:p></P>
<P>Server Spec POWEREDGE 1850 XEON 2.8GHZ/2MB 800FSB – WITH 2 GIG RAM and RAID
1 Configuration on two Disks RPM 10K… Its Running Fedora Core 5, Send Mail
8.13.8-1.fc5 with MailScanner 4.69.7-1 with SA, Razor, DCC., MailWatch
V1<o:p></o:p></P>
<P>Its working very well blocking spam, but only in the last couple of days its
got really slow. <o:p></o:p></P>
<P>Any ideas on how to reduce the load on this server>? By blocking mail at
the MTA before it hits MS? OR Tweaking my processes?<o:p></o:p></P>
<P>What do the Experts think on the Server Spec, for the amount of
traffic?<o:p></o:p></P>
<P>I’d appreciate any help<o:p></o:p></P>
