How can I determine if my IronPort appliance is using TLS for delivery or receiving?
Transport Layer Security (TLS) is a popular mechanism for enhancing TCP communications with privacy and authentication. The IronPort appliance can establish connections to remote hosts using TLS or require TLS when remote hosts establish connections.
TLS connections are recorded in the IronPort mail logs along with other significant actions related to messages such as filter actions, anti-virus and anti-spam verdicts, and delivery attempts. If there is a successful TLS connection, there will be a TLS success entry in the mail logs. Likewise, a failed TLS connection will produce a TLS failed entry. If a message does not have an associated TLS entry in the log file, that message was not delivered over a TLS connection.
Below are examples of successful and failed TLS connections:

We are using TLS for some incoming and outgoing mail. Is there a way to monitor the behaviour of the TLS mail. At this moment I can only find some TLS report afterwards.
I know that there are lines in the maillogs. I have also used spamtowho and in the output there are some lines about TLS connection. You can use the GUI (or CLI) to define TLS. What I want to know if there is a method to monitor the behaviour of TLS preventive.
This is exactly the question that I need an answer too aswell.
We are lokking at turning on TLS fairly soon, but need an easy way to monitor TLS just incase of failure, and also to be able to report on the volume of TLS connections that are happening.
I don't want to spend all day trawling through the mail logs. Is there either a report or somewhere within the GUI that we can monitor TLS?
Our Production Boxes are 5.5.1 at the moment but we are looking to upgrade to 6.1 when it is released (I think later this month)
We also have a test box is on V6.0 that were are currently testing TLS on.
We are allready using 6.1. There is a seperate display for TLS. I think you can ask support or your sales representative for this version to test.
I just read this thread and I think what people are asking is if you can get an alert as soon as TLS fails. This seems to be pretty important if you have a "Required" TLS connection with a partner. Reports are good for the end of the day, but email alerts are important to fix critical problems. Is this possible?
This feature is implemented in the newly released version of ASYncOS 6.5-405. TLS alerts can be configured under the destination controls setting.
I see it now. I did not have the latest version. Great feature.
Do you mean the Required - Verify (Preferred - Verify). This option is already in V6.4
