Good point! We are experiencing high CPU load during the day causing sendmail to defer and eventually reject messages. The delay before an email increases up to 2 minutes. Also, internal mail servers are not able to send email since the MX server defers and/or rejects email. Our CPU load has been increasing over time.<br>
<br>
I have received a few good tips e.g. create our own DCC server, commands for Bayes.<br>
<br>
We have plans to dedicate a MX server to outbound mail which should help.<br>

Subject: RE: Performance issues with MS and SA<br>
<br>
Hello Donald<br>
<br>
Maybe I'm a big thick headed but I don't see you mention what your performance issue is?<br>
<br>
You say you process 150k mails with 4 servers each with 4 cores (that's how I read it anyway)<br>
<br>
But what is the problem, are you incoming mail queues too big, or do you expect a quick increase in mail volume in the near future?<br>
<br>
Or do you simply want to optimize your setup, and don't have a problem per say?<br>
<br>
Cheers<br>
<br>
Med venlig hilsen / Best regards<br>
