Names with @dom.ain are explicitly NOT to be in IANA per
RFC 4250 section 4.6.1

...elided...
| 4.6.1.  Conventions for Names
| 
|    All names registered by the IANA in the following sections MUST be
|    printable US-ASCII strings, and MUST NOT contain the characters at-
|    sign ("@"), comma (","), whitespace, control characters (ASCII codes
|    32 or less), or the ASCII code 127 (DEL).  Names are case-sensitive,
|    and MUST NOT be longer than 64 characters.
| 
|    A provision is made here for locally extensible names.  The IANA will
|    not register, and will not control, names with the at-sign in them.
| 
|    Names with the at-sign in them will have the format of
|    "name@domainname" (without the double quotes) where the part
|    preceding the at-sign is the name.  The format of the part preceding
|    the at-sign is not specified; however, these names MUST be printable
|    US-ASCII strings, and MUST NOT contain the comma character (","),
|    whitespace, control characters (ASCII codes 32 or less), or the ASCII
|    code 127 (DEL).  They MUST have only a single at-sign in them.  The
|    part following the at-sign MUST be a valid, fully qualified internet
|    domain name [RFC1034] controlled by the person or organization
|    defining the name.  Names are case-sensitive, and MUST NOT be longer
|    than 64 characters.  It is up to each domain how it manages its local
|    namespace.  It has been noted that these names resemble STD 11
|    [RFC0822] email addresses.  This is purely coincidental and has
|    nothing to do with STD 11 [RFC0822].  An example of a locally defined
|    name is "ourcipher-cbc%example.com@localhost" (without the double quotes).

Please note that foo%example.com@localhost is a different extension than
foo%Example.COM@localhost due to the case-sensitive nature of the name.
(Yes, it is confusing.)
