Digitally signing mail sent from iPad
I need to send digitally sign email, which I do regularly from Apple Mail on my MBP by clicking on the little icon on the New Message window. I emailed the .pfx file to myself as an attachment and opened it on the iPad. This saved the certificate under Settings>General>Profile>My Name. However, I can't find any option/icon to digitally sign mail when sending from the iPad. Is there a solution? I have the iPad 2, iOS 4.3, and a .me mail account.
Thanks in advance.
