The mailing list for listmasters using Sympa

[Ian Miller <address@concealed>]

The message in question seems to have been generated by Sympa as notification 
of a new list being requested. Is this the same as sending  from the web 
interface?

It is likely that other parameters have been changed in sympa.conf (eg 
listmaster addresses, wwsympa_url, db details) . Are you saying that the 
checksum will always fail if the file is not original? Is there a workaround 
for this?

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.
