With S/MIME-signed and/or encrypted e-mails, to enable the success status of the decryption or verification of the signature to be returned, the following keywords are supported:
SMime-Decryption-Status
“NOT-ENCRYPTED” if the e-mail was not encrypted,
“OK” if it was successfully decrypted, otherwise a short description of the error
SMime-Verification-Status
“NOT-SIGNED if the e-mail was not signed,
“OK” if the e-mail signature was successfully verified, otherwise a short description of the error
SMime-Signer-DN
DN (Distinguished Name) of the e-mail signatory.
SMime-Signer-CN
CN (Common Name) of the e-mail signatory
SMime-Signer-E-Mail
E-mail address(es) of the e-mail signatory, comma-delimited; there may be several e-mail addresses in the case of X.509v3 certificates when an e-mail address is specified for both DN and SubjectAltName.
SMime-Issuer-DN
DN (Distinguished Name) of the certificate authority (CA) that issued the e-mail signatory certificate
In the case of multipart/mixed messages, the information about decryption and/or signature verification is only assigned to the message body text part, not the attachment parts. In the case of the latter, %SMime-Decryption-Status% is expanded to NOT-ENCRYPTED and %SMime-Verication-Status% to NOT-SIGNED unless the attachment is an S/MIME-signed or encrypted e-mail.
