Re: Sender header?

[Barry Fishman <barry_fishman@acm.org>]

Thanks for all the help.

Since I don't know how to respond to multiple useful messages at the
same time I'll try.  I think this is important since there must be a
many users that are comming in via ppp phone connections that consider
only windows machines.  I think the gnus manual should deal with it.
I didn't find anything.

I did!  Internet domain setup on unix requires a domain name.  Like most
people I don't want to buy one.  Rather than supply something that
looks correct, but isn't, I use local, which I think is clear in
meaning.  I don't spend all my time connected through att.net.  Even
when I am connected, I am not sure what my A record would be.  It does
not show up in my PPP/PAP dialog.

I've tried that. The just use the @ecube.local which they got from
my SMTP HELO, add their dommain and then the regular hashing.  I finally
decided to use a unique identifier (although not really a legal
domain name, my e-mail address.  It was just as unique and a lot
shorter. Stealing the idea from:

Here you are posing as another machine,  A sane person would
expect the Message-ID's to still be unique with all the hashing added.
However, I'm a programmer and would want to at least make my fqdn
unique and identifiable.

This seems better.  Personally I think that "Sender:" is like "From:"
and "ReplyTo:",  chosen by person/agent sending the mail and not
automaticlly produced.  Defaults are nice, but if gnus wants too
construct a "Sender:", it probably should be set to the person who wrote
the elisp that constructs a sender. ;)  Mail transport agents have their
own fields to fill in if they don't like the from field.

Until I can confirm a A record, I'll use the elisp:

;; I don't really have valid FQDN information so clean up header
(setq message-syntax-checks '((sender . disabled)))

(defun smtpmail-fqdn ()
   "Supply a domain which is meaningful but wrong (my email address)"
   "barry_fishman.att.net")

(defun message-make-fqdn ()
  "Supply a unique root for message id"
  (smtpmail-fqdn))                                                             

I have Kai's removal of Message-ID commented out since I think gnus's
Message-ID is much shorter.

This seems to leave behind the most meaningful mail headers.  Probably
too meaningful if you which to avoid spam.
