If "domain" and/or "cookie" parameter(s) have been changed,
checksum will fail.

Workaround is, as I wrote in the previous post, removing checksum
line generated with the older parameter(s).  The cecksums generated
with the new parameters won't fail anymore.

Or, the best solution is updating Sympa to recent versions which
no longer will use checksums.
