I recently configured SMIME for signing and encrypting outgoing mails on our OTRS system.
And that's working fine already. I can choose between SMIME encrypt / SMIME sign / SMIME sign and encrypt on the EmailOutbound mask.
Now basically my question is: can I set SMIME sign as default value in the EMailSecurity field?
I have pretty much looked at all settings in the Admin area and also in the SysConfig but couldn't find a suitable setting.
Maybe it's possible to configure it on the sendmail module?
OTRS version: 6.0.14
OS: CentOS 7.4.1708
I hope I'm just blind or something and you guys know a quick answer

Greetings
