Yes. It does not represent a document to be RETRIEVED
by mail (mail is not a retrieval protocol _really_).
The URL represents the mail address.
Sending a message to a mail address is the equivalent
function to posting an article to a newsgroup, or linking
an annotation to a document. There is a new object created
and an association made with an existing object.
A minor difference is that you can't read a mail address,
though you can read a newsgroup or an annotated document.

In fact, of copurse, a good client can do quite a lot to
_represent_ the mail address, with some kind of
icon and perhaps a list of messages the user has in her
some mailboxes which were from or to that mail address.
A current implementation (Cello) puts up a window
for writing messages to the mail address.
