Book:OTRS 3.0 - Admin Manual/Chapter 5/9

OTRS can process incoming S/MIME encoded messages and sign outgoing mails. Before this feature can be used, you need to activate it and change some config parameters in the SysConfig.

The "S/MIME Certificates" link on the Admin page allows you to manage your S/MIME certificates (see Figure 5.44 below). You can add or remove certificates, and also search through the SMIME data.
