TLS is the successor to Secure Sockets Layer (SSL). Gmail uses TLS by default, but when a secure connection isn't available (both sender and recipient need to use TLS to create a secure connection), Gmail will deliver messages over non-secure connections. However, you can configure your TLS setting to require a secure connection for email to (or from) specific domains or email addresses that you list. What happens to email to (or from) domains that don't use TLS? Outgoing mail Mail won't be delivered and will bounce. You'll get a non-delivery report (NDR). Only one send attempt is made (no retries). Incoming mail Mail is rejected without any notification to you, although the sender will receive an NDR. -- syafril ------- Syafril Hermansyah MDaemon-L Moderators, running MDaemon 18.0-64 bit Harap tidak cc: atau kirim ke private mail untuk masalah MDaemon.
