Hi, you wrote:

Strange! RFC822 is still uptodate according to RFC1920. Excerpt:

     message     =  fields *( CRLF *text )       ; Everything after
                                                 ;  first null line
                                                 ;  is message body
 
     fields      =    dates                      ; Creation time,
                      source                     ;  author id & one
                    1*destination                ;  address required
                     *optional-field             ;  others optional
 
     destination =  "To"          ":" 1#address  ; Primary
                 /  "Resent-To"   ":" 1#address
                 /  "cc"          ":" 1#address  ; Secondary
                 /  "Resent-cc"   ":" 1#address
                 /  "bcc"         ":"  #address  ; Blind carbon
                 /  "Resent-bcc"  ":"  #address

Obviously the destination is required.
How else could it have been sent to gnu-win32?
Note that RFC822 doesn't mention "Apperantly-To:" at all!
I can't easily grep thru all RFCs; so where is "Apperantly-To:" defined?

Bye, Heribert ([email-masked])
