I guess the user posted the message in question using web interface
(via "Post" menu).

The earlier version of Sympa (6.1.x or earlier) added a "checksum"
to the messages posted with web interface, and checked it to confirm
that the message had been posted properly.  Changing some parameters
including "domain" may invalidate this checksum.

At first, confirm that you haven't changed any parameters except
"domain" parameter: Compare "sympa.conf" file before and after changing.

If you can be sure, you can deliver the message doing as below:

  1. Stop the Sympa services.

  2. Edit the message in question left in the "bad" directory to
     remove a line beginning with "X-Sympa-Checksum:".

  3. Copy the message above into the parent of "bad" directory (Maybe
     it is "msg" directory).

  4. Start the Sympa services.

Hope this helps.
