While mailto: consumers have no compelling reason to split an address into LHS and RHS this could get tricky with the regular expression in the mailto.uri.arpa NAPTR Maybe mailto-bis should do something with the NAPTR, if it mentions the %40 magic as proposed by you: >| A mailto URI containing the percent-encoded octet "%40" >| in place of "@" in the addr-spec may be a valid URI in >| general, but does not conform to the mailto URI syntax. >| Interpretation of such malformed mailto URIs is >| implementation-dependent, but consumers of such URIs >| commonly regard them to be equivalent. RFC 2368 was based on 1738, and apparently 1738 allowed to percent-encode "@" where it's not reserved by the scheme. The problem of the percent-encoded comma might be related to your question (opposite issue, why not use comma as is) Frank
