IIS SMTP Not always use TLS for outbound RRS feed

  • Question

  • Hello,

    I have an IIS SMTP email relay server configured to use TLS for outbound traffic from inside my cage.  I have a couple customers that won't accept TLS traffic.  Is there any way to configure the IIS server to try sending emails over un-encrypted methods if encryption methods failed?
