Using Transport Layer Security for CSSMTP

  • 1.  Using Transport Layer Security for CSSMTP

    Posted Tue July 30, 2024 10:42 AM

    I have just started my research into using Transport Layer Security for CSSMTP.   When I enable secure mail, is this for all outgoing email or can the user choose if the message is secure or not?

    In z/OS Communications Server: z/OS V2R4.0 Communications Server: IP Configuration Guide, Chapter 26. Mail on z/OS, I found the following statement: 

    "Configure CSSMTP to require secure communication. Configure the TargetServer statement with the Secure parameter set to YES, which specifies that TLS protocols are always required."

    Is there a parameter a user may add to a batch job to enable or disable the use of encryption?
