S/MIME mime type application/octet-stream

Hello, i found that the file command detects S/MIME attachment (smime.p7s) within a signed email as an application/octet-stream insted of application/pkcs7. Author of the file tool tells that it's impossible to detect application/pkcs7. Does anybody knows why? Thank you Jan smime.p7s
