Utilising the "SpecifiedPickupDirectory" in the web.config ELMAH will not save emails to the specified folder

[GoogleCodeExporter]

Steps that will reproduce the problem:

1. Add the following section to your web.config in place of any other similar 
section:

<system.net>
    <mailSettings>
        <smtp deliveryMethod="SpecifiedPickupDirectory" from="[email protected]">
            <specifiedPickupDirectory pickupDirectoryLocation="C:\{Path}\App_Data\"/>
        </smtp>
    </mailSettings>
</system.net>

2. Trigger an exception that was previously being emailed by Elmah. 

I would expect the email that I would have received to be saved in the location 
specified in the web.config. Instead, the error is logged but no email is 
saved. I have tried the App_Data path as well as a new directory in the root of 
my C:\ drive, both with no success. I have set up a simple email method 
separate from ELMAH and this does save a copy of the email message to the 
specified directory.
