New function to decide if a mime part is an S/MIME v3 signed part.
2001-03-07 Jeffrey Stedfast <fejj@ximian.com> * mail-crypto.c (mail_crypto_is_smime_v3_signed): New function to decide if a mime part is an S/MIME v3 signed part. (mail_crypto_is_pkcs7_mime): New function to decide if a mime part is an application/pkcs7-mime part (or an application/octet-stream part with application/pkcs7-mime data). svn path=/trunk/; revision=8578
