我在验证时遇到问题一些Mutt 中的 S/MIME 消息。
首先介绍一下背景
$ mutt -v

和 Openssl：OpenSSL 1.0.0e-fips 6 Sep 2011
我正在使用smime.rc与 Mutt 捆绑的产品。
问题
[-- OpenSSL output follows (current time: Mon 26 Sep 2011 01:07:18 PM CDT) --]
Verification failure 30686:error:21075075:PKCS7 routines:PKCS7_verify:certificate verify error:pk7_smime.c:245:Verify error:unable to get issuer certificate
[-- End of OpenSSL output --]
据我所知，这种情况发生在属于加州签名的电子邮件发件人证书不在.smime/ca-bundle.crt
因此，为了进一步解决这个问题，我找到了属于这个人的证书，该证书已经使用 ^K 从 Mutt 中获取：
$ openssl x509 -in 5c400f68.0 -subject -issuer -out /dev/null
subject= /C=US/O=U.S. Government/OU=ECA/OU=VeriSign, Inc./OU=**REDACTED**/CN=**REDACTED**
issuer= /C=US/O=U.S. Government/OU=ECA/OU=Certification Authorities/CN=VeriSign Client External Certification Authority - G2
我似乎在我的根文件中有该证书：
$ grep 'VeriSign Client External Certification Authority - G2' ca-bundle.crt
Subject: C=US, O=U.S. Government, OU=ECA, OU=Certification Authorities, CN=VeriSign Client External Certification Authority - G2
