It just works.

I did some testing years ago and I honestly do not remember -
nevertheless we migrated to ZFS so either it wasn't slower or it was
faster.
I run exim (which is a pretty similar sort of MTA) on 2-3 year old
x4200's with ZFS mirrored on local SAS drives. These perform
better than they did with UFS due to the L2ARC. I have two of these.
Each one manages to process around 300-500K
inbound messages per day quite easily with Spamassassin running on them
as well. Spec is dual dual core Opteron with
4 GB RAM. 4 x 73 GB 10K 2.5 SAS disks.
As I think Tony mentioned, the best thing to do is to test with your
specific workload. I don't think you will see a drop
in performance at all. (and you will gain so many other lovely things
that ZFS brings ;))
