As a rule, I ban certain file attachments based upon extension (e.g., .exe).

If a recipient gets a message with a banned extension, they see something like the following in their email:

The message has been quarantined as: banned-GWrLVTg4ELXx

Please contact your system administrator for details.
I'm guessing an RFE is in order, BUT is there anyway to allow a single account to receive banned attachment extensions? If not, is there any convenient way for the administrator to access the quarantined message (e.g., as above: banned-GWrLVTg4ELXx)?
