Hi, It would be great to have an additional parameter to create the request for such a receipt in "openssl smime -sign" as per http://www.faqs.org/rfcs/rfc2634.html chapter 2.
It seems that MS-Outlook can do this since a while. Others seem to have struggled with validating such "smime-signed" receipt messages they received without resolution before: http://www.mail-archive.com/openssl-users@openssl.org/msg42751.html Other projects appear to have this challenge still ahead of them too: http://www.bouncycastle.org/devmailarchive/msg04034.html Any hint on which other open source packages might allow to create such a signature for the time openssl doesn't do this yet are highly appreciated.
