I am confused to be able to read my encrypted mail on my IOS devices (solved: was an S/MIME e-mail)

I installed the GPG Suite Beta 3 on my iMac that is running the latest version of Yosemite OS. I received an encrypted mail from my brother, which I am able to read on my iMac. What has surprised me is the fact that I can read the same mail on my iOS devices as well. It works on my iPhone and on my iPad which are not running any decryption app. So, I cross checked the web based mail app on my iCloud account if it got encrypted at all. There I find the mail with no content but a smime.p7m attachment as expected.
I would not have expected to be able to read the mail on my iOS devices. How is my iOS device able to decrypt the message? Or could it be that the Continuity feature of Yosemite copies the decrypted mail to all of my devices?
Sorry if I ask a question that had been asked before, but I was not able to find this subject in the discussion forum or the knowledge base articles.

All the best!

    How do you feel about taking a second look on your iMac and see if
    "the mail in question" shows an icon "locked" saying "Encrypted"

    I believe what you see in iCloud is mail sent using S/MIME not Open PGP
    does not mean it was "encrypted" per say but S/MIME was selected
    see the screen grabs to understand what I am attempting to illustrate

    I sent using S/MIME with GPG mail at 1:03AM
    and viewed on iCloud showing the unencrypted mail at 1:04AM

    notice on iCloud the smime.p7s thats the "signature file" to prove who sent it
    Hope that answers the question of what might be happening

    Please be careful and safe

    Hi Paul!

    You are right! It was an SMIME message that my brother sent to me. Now, with a real encrypted message, everything works like expected.
    Sorry for bothering you!

    Thank you for the great work that you are doing!

    All the best,
