Re: msg-id

[Frank Ellermann <nobody@xxxxxxxxxxxxxxxxx>]

No more nonsense before 12-24, I promise, but the proposed
msg-id-core syntax was just ugly, here's my "xmas-edition":

| msg-id-core     =  "<" unique "@" mdomain ">"
| mdomain         = dot-atom-text / ("[" address-literal "]")
| address-literal = 1*( atext / "." / ":" )    ; see RfC 2821

| unique          = dot-atom-text / ( DQUOTE unique-quote DQUOTE )
| unique-quote    = ( "." [unique-part] ) /
|                   ( [unique-part] "." ) /
|                   ( [unique-part] unique-literal [unique-part] )
| unique-part     = 1*( atext / "." / unique-literal )
| unique-literal  = "(" / ")" / "," / ; all specials, minus ">",
|                   "[" / "]" / "@" / ; minus DQUOTE, minus "\",
|                   ":" / ";" / "<" / ; minus single ".", plus:
|                   ".." / "\\" / ( "\" DQUOTE )
