It's most likely a poorly formed header in the e-mail. I reported this
to ThunderBird back in June and they said they will fix it in the next
major release <https://bugzilla.mozilla.org/show_bug.cgi?id=436869>
Look at the long headers of an encrypted e-mail and verify it has the
MIME type of application/pkcs7-mime

Has anyone seen the following behavior and identified a root cause
or a corrective action?
Several of our processes generate an S/MIME (encrypted/un-signed)
email message, which several of us read in Apple Mail (Leopard).
The message shows up just like an un-encrypted message, and doesn't
show the lock icon. Other encrypted messages show the (visual, not
email) Security header with the lock icon.
Senders using their (varied) email clients to send a message show
the lock. Perhaps of consequence is that the keychain also has the
sender's certificates.
The messages without the lock are sent from a scripted process, one
of which uses OpenSSL in FIPS mode. These messages do not have an
associated certificate for the sender (output-only email process).
Thunderbird and MS Entourage (2008) have no problem showing the lock
icon. Seems purely an Apple Mail issue.
