message.el: mail-host-address ignored

[Raymond Scholz <rscholz@tzi.de>]

Hi!

There seems to be an inconsistency in the behaviour of message.el
compared with it's documentation, coming with PGnus 0.98 .

My computer's name is "mde1". Some Linux distributions force the user
to specify a domain part too [1]. I used "home", so the complete name
is "mde1.home", no FQDN as you see. `system-name' gives me that string
too. So I set `mail-host-address' to a FQDN after consulting the
Message info pages and finding:

| `Message-ID'
|     This required header will be generated by Message.  A unique ID
|     will be created based on the date, time, user name and system
|     name.  Message will use `mail-host-address' as the fully qualified
|     domain name (FQDN) of the machine if that variable is defined.  If
|     not, it will use `system-name', which doesn't report a FQDN on
|     some machines - notably Suns.

But Message still uses `system-name' for Message-ID generation. My
tiny knowledge of Lisp tells me, that Message takes `system-name',
looks for a `.' in it and calls it fully qualified after that. If
there is no `.' in it, it uses other alternatives (including
`mail-host-address') to build a unique Message-ID.

My current workaround is to set system-name to "mde1" by now...

Cheers,
  Ray

[1] Yes, I know how to work around this, but others possibly won't.
