[horde] IMP: activate S/MIME

[Jan Niggemann]

Hi list,

IMP displays a signed email with the addition:
"Die S/MIME-Unterstützung ist zur Zeit deaktiviert, so dass die  
digitale Signatur nicht überprüft werden kann."
which roughly translates to "S/MIME support is currently deactivated  
and the digital signature can't be verified".

How do I activate the S/MIME support?
