As I said in another exchange, I can't use GPG Mail. I don't have buttons "star" to sign and "lock" to encrypt e-mail. I don't know why. I have to do it manually (right click > service etc...). And as I said, when I encrypt manually an e-mail with an attachment, the attachment is not longer in the e-mail at the decryption process. It's like the attachment is gone, deleted, erased or what ever, but it's not in the e-mail anymore.

You can use GPG Mail in trail mode for 30 days and then decide if you want to purchase GPG Mail Support Plan.
Once the trial expired you will be in Decrypt Only Mode. You will always be able to decrypt encrypted messages. Encryption and signing of new message as well as verification of signatures will no longer be supported.
So this explains why the verification is not automatically happening in GPG Mail.
