Can't sign in Mail.app with Thawte cert.

[michaelsanford]

I signed up for a free email certificate with Thawte, which contains an email address, which is configured in Mail.app (on Leopard).

I used Safari to fetch the certificate, which was added to my keychain. It added both a CA for Thawte, and a certificate bearing my email address.

However, Mail.app doesn't seem to recognize it. I don't get any indication whatever (the ✔ badge or the lock icon) that Mail has identified the certificate or associated it with my email address.

I've tried restarting Mail.app, no joy.

Any ideas what I'm doing wrong?

EDIT: Also my Thawte certificate doesn't appear in my “My Certificates” category in my keychain. I also tested and created a self-signed root certificate and it does work in Mail.app as expected, so it must be someting I've done wrong importing the certificate?

One of the workarounds I read about on the 'net was to use Mozilla (and I presume FireFox may also work) to download the certificate. Then, Mozilla apparently has the ability to export the certificate to a portable file format of some sort, which can then be imported into the Keychain in Mac OS X.

Once you've done that, it's simply a matter of making sure the email address in the certificate is identical to the email address entered in Mail.app, including case. "Johndoe@somewhere.com" is as different from "johndoe@somewhere.com" as a banana is to a jetliner.

It added the certificate to my keychain via Safari and everything (the first time). I wonder why that worked! (Thanks ElD )
