Hi,

for test purposes I've selected a certificate for signing and encryption for a domain. Now I want to disable signing. How to disable it? Encryption is easy, there are check boxes. But for Signing there is only a radio group. When I want to delete the certificate I get the message, that it is in use. How to fix all this?

Version: 4.1.0-0.

TIA  
Matthias

If a certificate is selected as a signing certificate for a domain, the  
certificate is "in use". If a certificate is "in use", you cannot delete  
the certificate until you remove the certificate from the domain. You  
can do this by opening the domain settings, then select S/MIME -\>  
signing certificate. On the "Select signing certificate for domain"  
page, click "auto select certificate". This will remove the signing  
certificate for the domain.

Kind regards,
