syntax.  The full name is not considered a comment, but an
optional part of the header line.  Either the full name is
omitted, or it appears in parentheses after the electronic
address  of  the person posting the article, or it appears
before an electronic address enclosed in  angle  brackets.
Thus, the three permissible forms are:

     From: mark@cbosgd.UUCP
     From: mark@cbosgd.UUCP (Mark Horton)
     From: Mark Horton <mark@cbosgd.UUCP>

Full names may contain any printing ASCII characters  from
space through tilde, with the exceptions that they may not
contain parentheses  "("   or   ")",   or  angle  brackets
"<"   or  ">".    Additional restrictions may be placed on
full names  by  the  mail  standard,  in  particular,  the
characters  comma   ",",  colon  ":",  and semicolon   ";" 
are inadvisable in full names.

2.1.4  Date  The Date line (formerly   "Posted")   is  the
date,  in  a  format  that  must be acceptable both to the
ARPANET and to the getdate routine, that the  article  was
originally  posted  to  the  network.   This  date remains
unchanged as the  article  is  propagated  throughout  the
network.  One format that is acceptable to both is

     Weekday, DD-Mon-YY HH:MM:SS TIMEZONE

Several examples of  valid  dates  appear  in  the  sample
article above.  Note in particular that ctime format:

     Wdy Mon DD HH:MM:SS YYYY



                          - 4 -
 




is not acceptable because it is not a valid ARPANET  date.
However, since older software still generates this format,
news implementations are encouraged to accept this  format
and translate it into an acceptable format.

The contents of the TIMEZONE field is currently subject to
worldwide time zone  abbreviations,  including  the  usual
American  zones  (PST, PDT, MST, MDT, CST, CDT, EST, EDT),
the   other   North   American   zones   (Bering   through
Newfoundland),  European  zones,  Australian zones, and so
on.  Lacking a complete list at present (and unsure if  an
unambiguous   list   exists),   authors  of  software  are
encouraged to keep this code flexible, and  in  particular
not  to  assume  that  time  zone  names are exactly three
letters long.   Implementations  are  free  to  edit  this
field,  keeping  the  time the same, but changing the time
zone (with an appropriate adjustment  to  the  local  time
shown) to a known time zone.

2.1.5  Newsgroups  The  Newsgroups  line  specifies  which
newsgroup  or newsgroups the article belongs in.  Multiple
newsgroups  may  be  specified,  separated  by  a   comma.
Newsgroups  specified  must  all  be the names of existing
newsgroups, as no new newsgroups will be created by simply
posting to them.

Wildcards (e.g., the word  "all")  are never allowed in  a
Newsgroups  line.  For example, a newsgroup  "net.all"  is
illegal, although a newsgroup name    "net.sport.football" 
is permitted.

If an article is received with a Newsgroups  line  listing
some  valid newsgroups and some invalid newsgroups, a site
should  not  remove  invalid  newsgroups  from  the  list.
Instead,  the  invalid  newsgroups should be ignored.  For
example,  suppose  site  A  subscribes  to   the   classes
"btl.all"   and   "net.all",   and exchanges news articles
with site B,  which  subscribes  to   "net.all"   but  not
"btl.all".      Suppose   A   receives   an  article  with
"Newsgroups: net.micro,btl.general".     This  article  is
passed  on  to  B because B receives net.micro, but B does
not receive btl.general.  A must leave the Newsgroup  line
unchanged.   If  it  were  to  remove  "btl.general",  the
edited header could  eventually  reenter  the    "btl.all" 
class,  resulting in an article that is not shown to users
subscribing  to   "btl.general".    Also,  followups  from
outside  "btl.all"  would not be shown to such users.

2.1.6  Subject   The  Subject  line  (formerly    "Title")
tells  what the article is about.  It should be suggestive
