"Mail wants to sign using key 'privateKey' in your keychain".

I can't send email because a pop up window says "Mail wants to sign using key 'privateKey' in your keychain" and asks for a password. What password? Please send solution.

It's the password for your account. The key would be a certificate you have registered to your email account.

Or, just disable signing of your email. There should be a button in the headers.
