I've never tried it but, the INFO LISTOWNR states:
 
  - The list name must be present, and it ought to be the first non-blank
    line of  the header. It  must not contain  any "=" character.  In the
    case that the  list name contains characters which  are considered as
    "special characters"  in RFC822 terms,  the list name must  be placed
    within  double  quotes,  eg  "The  IBM 3278,  3279  and  3180  list".
    The list name should not be so long as to cause the "Sender:" line to
    exceed  80 columns;  otherwise it  will not  appear on  the "Sender:"
    field.
 
    RFC822 "special characters" are: ()<>@,;:\.[]"
 
(I've seen at least one e-mail userid that ends in a plus sign.
(Different strokes for different folks/userids? ;-) ) )
