Interestingly - when the mailling list sent my own signed message back it failed verification! the 2 parts that are signed - first is a suite of headers - one of which is sender - the mail list manager replaced the sender header removing the original one (with my email address) and replacing it with fedora-bounces. Of course this cannot be verified anymore. This suggests that the Sender: field should not be signed - for mailing lists anyway - From and the remaining fields could continue to be used.
