Re: [Declude.JunkMail] Overflow directory and a note about Windows 2003 DNS

[Matt]

John, I do recall seeing this stuff, but I came away with the impression that it was only applicable if you were behind a particular type of firewall that had issues with the size of the packets or something to that tune.  If this was causing many timeouts, I would have seen a slight increase in spam getting through I would think, but nothing out of the ordinary has occurred that I am aware of. It is possible however that the new capability of the Windows 2003 DNS server is what is causing the extra processor utilization, and I don't think that I benefit from having it on, so I'll try turning it off using the registry hack and then see if it makes any difference.  I'm also going to look at what ways if any are available to tune the cache in DNS, thinking that a substantial difference here might also be an issue.

If there is more than 1 IP on the server, Imail was sending DNS tests requests (ala Imail Anti-Spam) on one IP and the response was coming back to a different IP in Windows 2003 DNS service. This was a minor problem, and was never known to affect Declude that I can remember. 2. Windows 2003 DNS service added/changed configuration which the end result was the length of the data was greater than it should be and that was causing problems. Again, this is in the Imail archives. If I did not have so much work right now, I would help did them up as I was one of the persons involved in investigating it. Fixes were registry settings.

On a side note, I was forced to do a rebuild on a backup server running Windows 2003. The DNS.exe process is a big-time dog compared to that on Windows 2000. I'm seeing DNS.exe reach over 50% of CPU utilization at times, and it never really drops below 10%, and I can't recall ever seeing DNS.exe on Windows 2000 ever go past the low single digits. No Active Directory on either machine, the processor power, memory and mail volume also. The only difference is the RAID card and only three 15K RPM drives in RAID 5 instead of six. Unless there is something unique to my environment, I would stay away from Windows 2003 DNS when used as a caching server with Declude/IMail, or for that matter, any possible high volume use of DNS on that platform.
