[gpgol] how to check if a message is encrypted or not?

[Bo Berglund]

If I open a message in Outlook (using the GPGOL plugin) and I see the
PGP block then I can use the decrypt button to see the decrypted
message. I am requested to enter my passphrase first.
But when I then look at the next message it is automatically decrypted
for me without entering the passphrase and I don't see the PGP block
anymore.

So how can I look through a number of messages to see which ones are
encrypted and which are not? As soon as the passphrase has been
entered once it seems completely transparent, all messages look alike
even those I *know* are encrypted!
