Thanks Til,I test renew certificate.But is can not read the old email that that encrypted with the old certificate.But I am not confirm this result,so I email to you to see if you do this before.-:).
I think it is can't work now.but I think this problem is not come from the renew certificate itself.Because the email that encrypted by the renew certificate can by read use the old key.I think the problem comes from email client,just like outlook,when outlook decrypte
email.He want to find the certificate that encrypted this email.but can't find,so it can't decripted this email.But I don't comfirm my guess is right.-:)
Best Regards.

Well that question is not so easy, as i didn't made tests with
that. But i think, it will not work. I have not the deep view
into encryption, but it maybe could work, if the keys of
the new certificate are the same as the old one. Maybe some of
the developers with more knowledge can make a clear statement.
You can test that very easily, just export the old certificate,
delete it in your store and the try to read emails.
