I went and checked 822 in the hopes of killing this thread before it wells up. :/ Essentially, 822 doesn't allow it. People use it with tools like dig/host/etc. coz they're used to having that form short cut the resolver. W/o the resolver hack, the trailing period indicates the root domain and is therefore superfluous. It's illegal in mail. The evidence follows, -Sudish [ Severely edited, from RFC 822 ] address = mailbox mailbox = addr-spec addr-spec = local-part "@" domain domain = sub-domain *("." sub-domain) sub-domain = domain-ref / domain-literal domain-ref = atom atom = 1* specials = "(" / ")" / "<" / ">" / "@" ; Must be in quoted- / "," / ";" / ":" / "\" / <"> ; string, to use / "." / "[" / "]" ; within a word. [ I.e., no "."'s in sub-domains, and all except the first subdomain are preceded by "."'s ] [ From paragraphs 3 and 4 in section 6.2.1 of 822, "Domains" ] The root node is common to all addresses; consequently, it is not referenced. [...] The "top" of the domain addressing hierarchy -- a child of the root -- is indicated by the right-most field, in a domain specification. [...]
