In any case, there is a further problem that RFC 3977 is much more generous
in what it allows:

    message-id = "<" 1*248A-NOTGT ">"
    A-NOTGT    = %x21-3D / %x3F-7E  ; exclude ">"

I can see that this leads to an ambiguity when there is no at sign in the
message-ID. Therefore I suggest:

    article  = 1*mid-char "@" 1*mid-char
    mid-char = unreserved / pct-encoded / sub-delims / "@" / "/"
    unreserved  = <defined in RFC 3986 section 2.3>
    pct-encoded = <defined in RFC 3986 section 2.2>
    sub-delims  = <defined in RFC 3986 section 2.1>
