NFS & IMAP... Acting very bad.

It all checks out.  And for NFS I am using IP not DNS.  I re-checked all 
my switches as well.  Lucky, i guess, I was sitting next to the servera, 
disk server, when I was checking my mail today and noticed it was 
accessing the disk a lot.  More than I would believe mail would need.
