I'm trying to resolve an I/O problem on a CentOS 5.6 server. The process basically scans through Maildirs, checking for space usage and quota. Because there are hundred odd user folders and several 10s of thousands of small files, this sends the I/O wait % way high. The server hits a very high load level and stops responding to other requests until the crawl is done.

setting 'noatime' for the mount options for partition holding the files will reduce the number of required I/Os quite a lot.

Yes, but before doing this be sure that your Software does not need atime.
