With two email applications, trying to verify your email I've received
via the mailing list, I'll get an "invalid signature".
One application is Mutt 1.10.1.

To debug this, you can
 * try to verify the email you've gotten back from the mailinglist
   yourself. (If you do not get any, use a different mail account
   or enable copies of your own emails in the mailman options for you.)
 * use a different application than yours to compare creation
   and verification of OpenPGP/MIME messages
 * Compare the email that you have received from the mailinglist
   with the one that still verifies (e.g. in your outgoing folder).
   Sometimes mail transport (SMTP or Mailman) will break signatures
   usually because some email standard property was not fully followed.

Regards
Bernhard
