Entrust Email Signing Certificate configuration... Cannot send signed email. CA is trusted. Help!

Purchased digital certificate to sign email messages. I get the "Unable to sign message. Please check that the certificates specified in Mail & Newsgroups Account Settings for this mail account are valid and trusted for mail."

I have downloaded every certificate from Entrust and added it to the store. I have confirmed each certificate is used for email signing. I still get the message.

Is there a solution? The program works great with Enigmail and PGP.

You say you "added it to the store" - which store? And how?

The last time I got a certificate for use with s/mime, it was delivered to my browser, and to get it into Thunderbird where I really wanted it, I had to export it from Firefox and import it into Thunderbird.

Whilst your OS might recognise it as a key or certificate and volunteer to add it to the system keystore, this won't necessarily be available to Thunderbird.
