All of that is good advice -- but one extra thing drew my attention -- IMAP running 99% CPU -- in my mind that points to possible file system issues - What shape your file system is in: Is it badly fragmented? Are any of your drives performing badly? Also - has someone suddenly changed what they are doing in IMAP that could cause heavy IO loads?
One system I helped on recently was slowly sucking itself into it's own private circle of hell along with it's admin. I followed the performance trail to the IO and found that a couple of large log files were very badly fragmented -- I moved those files to a new location and everything perked up right away.
* File moves often evaporate fragmentation.
* Files that grow slowly over a long period on a mail server on NTFS tend to get badly fragmented.

1) Are they just q files or d files or both? 2) Tripple check the DNS server(s) being used for problems. 3) Do you have a lot of large mailboxes? Has the amount of email flowing in increased? 4) Review information on the Sniffer list about updating to the new service model. Also, what version of Imail, what version of Declude?
