Can you try enabling RT's S/MIME support, and see how that improves
things?  See:

http://docs.bestpractical.com/RT_Config.html#Cryptography
http://docs.bestpractical.com/RT/Crypt.html#CONFIGURATION
http://docs.bestpractical.com/RT/Crypt/SMIME.html#CONFIGURATION

The following should be a minimal implementation:

    Set( %SMIME,
        Enable => 1,
        AcceptUntrustedCAs => 1,
    );

    Set(@MailPlugins, 'Auth::MailFrom', 'Auth::Crypt' );
