Not really -- OpenPGP does not reveal anything about the identity of the
encrypting entity. If the mail provider signed the email, it would be
noticeable, but there is no requirement to sign encrypted emails.
This can be solved by having the sender also sign the key used to encrypt
the e-mail. No idea how much work it is to add this.
