Try ^K, which is the default keybind for `extract-keys`.
This command extracts the public key and adds is to your keyring 
(smime_keys).

Also check the config options `crypt_verify_sig`, and 
`smime_verify_command`, `smime_verify_opaque_command`
When receiving a smime signed mail, mutt tells me if the signature is 
valid or not.
