With your earlier situation, I would have assumed that the I/O wait was the
result of activity on the disks holding your paging spaces. However, if
you've now eliminated paging that wouldn't be the case. (Of course, that
depends: what do you mean by "hardly doing any paging"?)
IO waits are not necessarily disk: another possibility is network. As this
is a mail server, that seems worth investigating.
