Mails with p7m-encryption


We are beginning to receive mails with a smime.p7m encryption.

My GW client can't open them, but states we are missing a encryption key.

But the sender says, it should open like a regular mail, unless we have an old certificate installed on the PC.



I have tried to open it on a completely clean PC (Win7), but I still get the error.



Is there a setting somewhere in GroupWise, that will allow me to open these mails?
