If you have LSMTP, you probably shouldn't turn EMM on. Overall, you might
gain some application CPU cycles (probably not with Classic though), but on
the other hand you would be creating and deleting a lot of individual files,
which would cost system CPU cycles. Windows and Linux have gotten better at
dealing with very large numbers of files, but there is still a cost for
creating these files. Of course, with a modest workload, you probably
wouldn't notice a difference either way.
