How do I change the From: line? I have set gnus-user-from-line to Gail
   Gurman <gail.gurman@sybase.com>, but XEmacs Gnus doesn't use it.
   Instead it uses Gail Mara Gurman <gailg@deall> and then complains that
   it's incorrect. Also, as you perhaps can see, my Message-ID is screwy.
   How can I change that?

   Set user-mail-address to gail.gurman@sybase.com or mail-host-address

   What can I do, if I get this 'misconfigured_system_so_shoot_me'
   Message-ID when I try to post something?
   
   The solution is the same as for the above problem. Set either
   user-mail-address or mail-host-address to the correct value.
   
   In Gnus 5.4, the error message was changed to make this fix more
   obvious. The Message-ID, instead of saying that your system is
   misconfigured, will tell you to set mail-host-address.
   
   Please note that this also works with ISO-Latin 1 characters like:
(setq user-full-name "Finn Håkansson")
