Jeff,
RFC 1630 make pretty clear that a email address in either a "mailto:"; or "cid:"; clause *is* a URI. It does not address whether a bare email address would count (it seems that it doesn't fit the RFC definition, but does fit some other I found by Goggle).
I could be convinced either way from a bare address (as it stand now, maybe someone else has something to add). But a "mailto:"; "mail:" or "cid:"; clause should (in my opinion) be looked up by the URI rules - they are URI, not URL rules (though URLs are clearly the most common from of URIs).
I was surprised to see that from the RFC, even "Msg-Id:" clauses are URIs.
Paul Shupak [EMAIL PROTECTED]
I'd agree with Paul, what's the difference between doing the lookup of the domain listed in a mailto: link and a http: link -- both of which are often found in someone's signature?
Eliminating the mailto: domain lookup could lead to spam such as "email us at [EMAIL PROTECTED] for all the junk you don't really want".
