message-user-mail-address and other addresses

[Hallvard B Furuseth]

(message-user-mail-address) in message.el seems to think that
user-mail-address can contain more than just the address, such as
"name <address>".  This is wrong, and if we teach users to put "name
<address>" in user-mail-address, packages that expect a plain address
will fail.  Examples: sendmail.el, add-log.el, rmailsum.el.

But if that's the idea, (message-user-mail-address) does not work
correctly anyway:
	(let ((user-mail-address "Hallvard Furuz <hbf@usit.uio.no>"))
	 	 (message-user-mail-address))
	==> "<hbf@usit.uio.no>"
oops, should remove the <>'s.  This works, however:
	(let ((user-mail-address "hbf@usit.uio.no (Hallvard Furuz)"))
	 	 (message-user-mail-address))
	==> "hbf@usit.uio.no"

Also, it does not allow for "foo!bar!baz" type addresses.

BTW, I haven't checked but I hope all your mail-address code allows for
addreses like these (real-life) addresses:
  @bsd.urgu.e-burg.su,@optoel.uucp:aleck@optoel.urgu.e-burg.su
  /S=ZHAOQING.LTD/O=SERVICE/PRMD=JMPTT/ADMD=CHINAMAIL/C=CN/@x400.bta.net.cn
  sevcik@[147.231.40.1]
  Egon_Hagen_at_ROGALAND__A-SENTER@cclink.rf.no
  idgst1+@pitt.edu		(note: end of localpart is not end of word)
Some real-life idiot addresses:
  "gry oftedal"@nlhstud.nlh.no	(stupid, but some people do that)
  ingrid.haug.@nlhstud.nlh.no
  Joern..Nicolaisen@hinesna.no

Huh. Space in localpart is actually "sensible" in one case:
  "/I=hb/S=furuseth/OU=usit/O=uio/PRMD=uninett/ADMD= /c=NO/"@mons.uio.no
i.e. mail sent to an X.400 -> rfc822 gateway.  X.400 addresses, in
particular their ADMD parts, sometimes contain space.

Oh, and here is one more.  Is this address nuts or am I missing a
message format?  It's the envelope (`From ') address of a message to
directory@uninett.no:
   hsba1@dagobert#u#br.ccmail.compuserve.com

That's true.  However, many (many) people, especially people mostly
using XEmacs, it seems, have a `user-mail-address' that contains more
than just the address.  I don't normally think one should cater to
brokenness, but in this instance there were just too many people that
experienced problems.

Yup.  0.74 will use `mail-extract-address-components' to extract the
address parts.  I think it does a good job.  I tried it on all the
examples you gave, and it failed only on one:

>   @bsd.urgu.e-burg.su,@optoel.uucp:aleck@optoel.urgu.e-burg.su

(nth 1 (mail-extract-address-components
"@bsd.urgu.e-burg.su,@optoel.uucp:aleck@optoel.urgu.e-burg.su"))
 =>
"aleck@optoel.urgu.e-burg.su"

Perhaps one should send a bug report to the mail-extr people?

Great!  And sgnus itself no longer contains any regexps that will fail
if there are, say, spaces in an address?

No, I think that's correct.  The @foo: stuff appears to be routing
information on the `From ' line.


BTW, about (user-mail-address): Erik Naggum thought the best way was
	(defun user-mail-address (...)
	  (or (and user-mail-address-function
		   (eq user-mail-address user-mail-address-default)
		   (apply user-mail-address-function ...))
	      user-mail-address))
where user-mail-address-function is *not* encouraged to set
user-mail-address, but instead does it own bookkeeping.

Hum.  Well, if we are going to un-break these as far as possible --
How do they write those addresses?  Is there some "semi-standard" for
XEmacs on this?  If it's
	"one@address, another@address",
then
	From: Joe Luser <one@address, another@address>
won't work too well...
Maybe we should fix add-log & such things instead...

RFC822 only permits source-routing inside angle brackets.  I don't think
this address is legal.  Also, I don't think the path components are
separated by commas.  The `@' symbol is the separator.

from RFC822:

route       =  1#("@" domain) ":"           ; path-relative
route-addr  =  "<" [route] addr-spec ">"

Well, it's legal inside angle brackets then:-)

Huh.  RFC821 uses routes with comma:

                  TO:<@HOSTA.ARPA,@HOSTB.ARPA:USERC@HOSTD.ARPA>

Umm - Does anybody remember which RFC lists recommendations for various
services, including errors in previous RFCs?

It seemed to respond correctly to addresses with spaces.  I took a
peek at `mail-extr', and it said they had over 100K test cases, so it
would seem that it's quite thoroughly tested.  (It's written by JWZ,
by the way.)

The lesson I've learned from this:  "Don't *ever* try to come up with
my own regexps for mail header recognition.  Someone else will have
done the job properly for me."

Doh.  That's patently wrong.  The rest is, I believe, correct.
