TLS for what? All of our servers encrypt their internal communications with TLS is that what you mean? Our external traffic is all encrypted with SSL (OWA, EAS, OA).
If I was relaying external SMTP traffic (which you would REALLY have to sell me on as to why you need it) I would definitely be using TLS to secure it. Reasons people might not use TLS: 1) Don't want to buy a certificate 2) Requires more client setup (though this is trivial) 3) Legacy MTA doesn't support it ? (not applicable for recent exchange versions) Is that what you are looking for? -troy -----Original Message----- From: mqcarp [mailto:mqcarpen...@gmail.com] Sent: Wednesday, January 14, 2009 9:05 AM To: MS-Exchange Admin Issues Subject: Easy Wednesday Question: TLS Do you use TLS on your Exchange server?
