I am using caching dns, ram disk for processing, clamd, compiled<br>
spamassassin rules and optimized scheduler and filesystems in this<br>
server. Any ideas on how I can tweak the above settings to gain more<br>
MailScanner performance?<br>

Set 'Log Speed = yes' in MailScanner.conf; then plot the average time spent per message. This is the key metric when tuning; it should be < 10 seconds and preferably 2-3 secs.<br>
<br>
That's the most important thing to do *first*. That way you can measure the difference once any tuning has been done.<br>
<br>
By far the most heavyweight process is going to be SpamAssassin - so that's most likely the area you are going to need to focus on. Are you using Bayes? If so - using which storage method?<br>

<br>makeing sure you're only hitting RBLS you have local zone transfers for etc will help alot if you've not already done that.<br clear="all"><br>-- <br>Martin Hepworth<br>Oxford, UK<br>
