I have not upgraded to fix the 2005 spamheaders test as of yet. Our CPU has been maxed out and the server bogged down since my return after the New Year. I have commented out the spamheaders test and the CPU is still maxed. I went into IMAIL and changed the delivery application from declude.exe to smtp32.exe and restarted the SMTP service and the processing dropped from 100% to approximately 13% - 20%. I placed the declude.exe back in as the delivery application and the processor utilization shot right back up. This narrows it down to declude however, I have not yet pin pointed exactly what is causing the increase in processor usage.
When you go to the Process tab in the Task Manager, and click on the CPU button, which process(es) are nearest to the top?
Note that this should not be related to the SPAMHEADERS issue.
Did you make any changes to the Declude configuration recently (such as adding filters, which can eat up CPU time, depending on what they do and how they are designed)?
I don't want to go through and comment out each test one at a time to find which the offender is.
If it does come to that, you can do it the "binary way." First, comment out 1/2 the tests. If the problem continues, uncomment the ones you just commented out, and comment out 1/2 of the ones that you did not comment out (if the problem does not continue, do the opposite -- uncomment 1/2 of the ones that you commented out originally). If you have 30 tests, you'll only have to do this 5 times. The drawback is that during the few minutes you are doing this, spam is more likely to come through.
