Hi,

somehow I cannot decrypt some S/MIME encrypted mails created with Thunderbird.
It works just fine with mutt, so it's not a problem with gpg[sm].

Not sure if they are relevant, but here's an excerpt of the headers:

User-Agent: Mozilla Thunderbird 1.0.7 (Windows/20050923)
MIME-Version: 1.0
To: Carsten Pfeiffer <carsten.pfeiffer@first.fraunhofer.de>
Content-Type: application/x-pkcs7-mime;
  name="smime.p7m"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="smime.p7m"
Content-Description: S/MIME Encrypted Message
X-UIDL: Zm=!!H;e"!Rmo!!+;,!!
X-UID: 12756
X-Length: 4087
Status: R
X-Status: NC
X-KMail-EncryptionState:  
X-KMail-SignatureState:  
X-KMail-MDN-Sent:  

Thanks,
Carsten

Thank you for taking the time to file a bug report.

KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
