[Evolution] Evolution generating invalid message-ids

[Gerald Oskoboiny <gerald impressive net>]

Hi,

I have received email with invalid message-id's from a number of
Evolution users recently; sample msgid:

    1023735423 7339 8 camel dirk

I did a bit of googling to see if this has been fixed in the most
recent versions, and can't find any evidence that it has. I found
what seems to be a related thread [1] that referred to bug 1557 [2]
and an expired i-d on guidelines for generating msgids [3] which is
worth reading; also, RFC 2822 says:

   The message identifier (msg-id) itself MUST be a globally unique
   identifier for a message.  The generator of the message identifier
   MUST guarantee that the msg-id is unique.  There are several
   algorithms that can be used to accomplish this [...]
   -- sec 3.6.4, http://www.ietf.org/rfc/rfc2822.txt

This problem might happen only on systems with misconfigured hostnames
(i.e. systems on which 'hostname --fqdn' returns a simple hostname
instead of fully-qualified domain name?), but I think it would be
good for Evolution to detect and handle this situation to prevent
sending out mail with bogus msgids.
