When you install Novell Vibe, you can choose whether or not the Vibe internal mail host uses TLS (Transport Layer Security) when it communicates with other SMTP mail hosts. For more information, see Inbound E-Mail Security
in Basic Installation
in the Novell Vibe 3.4 Installation Guide.
If your Vibe site needs to send e-mail messages to an e-mail system that requires secure SMTP (SMTPS), the Vibe site must have the same type of root certificate that is required for secure LDAP (LDAPS). If you have not already set up secure LDAP for your Vibe site, follow the instructions in Section 39.1, Securing LDAP Synchronization to set up secure SMTP for communications with your e-mail system.
