Hello, I recently got Digital Signature/Certificate from https://tcs-ca.tcs.co.in. I followed their instruction for downloading the key in windows internet explorer and taking backup of the same in .pfx format. Now, I want to use the same in our evolution. How to do it? I imported the same into evolution at Edit>Preferences>Certificates>Yours and added the same for S/MIME at Edit>Preferences>Mailaccounts>Security. Still I cannot sign and I get the following error: Because "Cannot add SMIMEEncKeyPrefs attribute", you may need to select different mail options. Where do I go wrong? Is it not possible to use the certificate in linux since it was generated in windows? BTW, I could use the same in outlook express - no problems. Please help. Thanks in advance. Rajesh
