My busy recent schedule and schedule ahead will result in this being added to my to do list which wont be started soon unfortunetly.
If its needed fast your best bet is to ask a coder to do this in the paid requests forum.
Boy, that's a shame.
Even worse is that other coders or developers here on vB.org might've passed up the opportunity because they saw that you were looking into doing it and didn't want to step on your toes.
Hopefully, any developer/coder that takes on this request will commit publicly only after they (schedule-wise and ability-wise) confirm that they can.
Its worth noting that inside the visitormessage.php script there is a comment (from the vB devs) that email notification should be added in so I'd suspect we see this sooner or later. Not that it helps people for today...
I should also note that visitormessage.php is missing a hook in the ajax routine which means either a code edit has to be made for this OR the email is sent before the message is truly verified as being posted. Neither is ideal.

I tested both the AJAX quickreply function and the Advanced (Go Advanced) option for posting visitor messages. The mod seems to work fine for both.
