I looked at SMIMEv2 and SMIMEv3 specs but I can't find the reference to
looking at From: and comparing it to certificate owner. Perhaps that's
simply obvious, altough I can think of some issues (use
X.509 subjectAlternateName or not? etc). Ok; CTL is required, From will
be needed, To will be needed by encryption/decryption.
Verifying signatures without checking that the sender == signer is of
course bad. OpenSSL doesn't seem to perform this checking (although it
has "-from" and "-to") so we have to do it ourself. Hm, are there any
ASN.1 libraries written in elisp? We'd might use
`ssl-certificate-information' of ssl.el as an easier solution.
