Message-ID

Message-ID

[Harry Putnam]

Every time a discussion about What the RFCs have to say about how mail
headers look.  I end up thoroughly confused.

Its my understanding that the part of the message ID after the
ampersand is supposed to be a real pingable address.

In my case it is being generated as the name of my home lan,
chub.local.net or one of the other <machines>.local.net.  Thats how I
set up the network.

These are not pingable outside my local net since I'm a dialup
customer to a "real" ISP.   I have set sendmail to masquerade my
POP and SMTP providers domain "newsguy.com" and to masquerade the
"envelope" .  Still this private local domain is escaping onto the
internet in my message-ID.

I imagine Gnus can be made to generate message-IDs that say:
xxxxxx-fsf@newsguy.com  or something similar, but not sure if that is
desireable either.

Or is it misconfiguration on the machine?  If so what needs to be
changed?

No, it's sufficient if it's a fully-qualified domain name.  You don't
need to have a DNS entry for the FQDN, but it's better if there's
an MX record (for mail delivery).  An A record (`pingable address')
is certainly not required.  Of course, the FQDN must be from a name
space under your control, otherwise you can't guarantee the uniqness
of the message IDs (which is required for news articles).

What about the following situation.  I'm using PPP with dynamic IP.
While offline I'm posting to a local queue which is flushed once the
PPP connection is on.

  * stage #1: At the moment of posting, FQDN is junk-name.isp.com
    since PPP is off.  No DNS entry exists for junk-name.isp.com.  It
    seems impossible to assure the uniqueness of Message-ID since
    someone may very well choose the very same junk-name, post at the
    very same time, using the very same uid, MUA, etc, etc.

  * stage #2: At the moment of sending the message to ISP, FQDN is
    dynamic-name-isp-gives-me.isp.com, which is a DNS-happy name.
    Good, but it is too late to create Message-ID since the post has
    already been queued before.  Since Message-ID attribution already
    happened, it does not seem to be a good idea to rewrite it with
    the new hostname, for several reasons; e.g. someone could have
    used it while I typed my message off-line so we may find the same
    uniqueness problem as described above.

Should the Message-ID creation be left completely to the ISP level and
not dealt with locally at all, neither by MUA nor MTA?

Contact your ISP.  Describe the situation to them.  Ask them what to do
about it.

That's okay.  A msg id must be unique.  So, you put your local host
name after the @ and something locally unique before the @.  Maybe
your ISP generates the msg id when using mew?

Gnus uses the system-name function to retrieve the local host name.  For an 
Internet node, this must be a fully-qualified domain name.  If it is not,
your system is not properly configured to be an Internet node, and you get
the 'totally-fudged-out-message-id' as a direct result.

Oops. I already setted up hostname and domainname for my desktop machine 
though...

********************************addition*******************************

I'm a user of Mew and when I send a mail in Mew, Message-ID is made 
like this: 
  
  year month day time loginname @ ISP's domain name

As for Gnus, Message-ID is as follows:

  something @ local hostname.local domainname  

# Both're quiet different :-(

On a properly configured system, no.

It means your system is not properly configured.  Your system does not know 
its own fully-qualified domain name.

I don't need to care about it, do I ?

Re: Message-ID

Gnus manufactures Message-IDs directly, to make sure they exist when
needed.  The Message-ID you describe is correct, because it properly
denotes where the message originated.  It is only the case that mail
relays generate Message-ID when the origin client mailer has failed to 
provide it.

If you really want to disable Gnus' generation of Message-ID, modify
variable message-syntax-checks to disable Message-ID.

Message-ID

[Shigeki Uno]

 Hello all. 

I'm new to this Gnus Mailing List. I'm running XEmacs-21.2.13 on
NetBSD/mac68k 1.4_BETA and sometimes write e-mails with Gnus 5.6.45
on XEmacs-21.2.13. 

I wrote a e-mail and sent it myself for checking whether everything goes 
well or not the other day.  I read recieved mail via another main mail 
program called "mew" and found that Message-ID is wrong. Usually Message-ID 
is made like this: 86btft51j2.fsf@provider's pop server name or domain name.
Right ? But as for e-mail which I sent, Message-ID is like this:
86btft51j2.fsf@lc520.shigenet.jp. 

lc520 is hostname for my desktop machine and shigenet.jp is domainname for
may desktop machine. I connect to Internet via internet service provider
using ppp connection. ISP's domainname is "mediawars.ne.jp" and pop server's
name is "mail.mediawars.ne.jp".

What's wrong with that ?  Any suggestions, please.

Thanks,
