the reason why I was asking; there it shows, that Mozilla Thunderbird 
above 10.x are capable of verifying such e-mails;
I recently got such an e-mail and it could not be verified; Thunderbird 
has shown an error; the certificate used for signing that e-mail
also used an sha256-hash, too;
at work I had a client capable of sending sha-256 hash signed e-mails, 
but only a sha1 cert; and that mail could be verfied without problems;

could someone please send me an email, where both the mail signature and 
also the certificate have a sha256 hash;
