Microsoft Exchange 2007 - SSL/TLS Setup
- These instructions assume you have already setup your AuthSMTP send connector in Exchange 2007 using the instructions on the Exchange 2007 setup page .
- Microsoft Exchange 2007 has a new feature called 'Opportunistic TLS' which is enabled by default upon installation, this feature means Exchange 2007 will negotiate a secured SSL/TLS session wherever possible and encrypt the message. Further information can be found on Microsoft's Technet Website .
- By default SSL/TLS is not enabled on AuthSMTP accounts, if you do wish to enable it you can do so by logging into the control panel and adding that feature, it is important that you read the notes about enabling it and using SSL/TLS as it does have some significant implications with regards to sending email and the way encrypted messages are counted towards to your account quota.
- If you do wish to use SSL/TLS please login to the control panel and enable it on your account.
- If you do not wish to use SSL/TLS you will need to take the following steps to disable this feature in Exchange 2007.
- Open the 'Exchange Management Shell'
- Type the following command to get a list of all your send connectors
- To disable 'Opportunistic TLS' you will need to enter the following command
Set-SendConnector -Identity "AuthSMTP Connector" -IgnoreSTARTTLS$true
- To confirm the change has been accepted you can enter the following command
Get-SendConnector "AuthSMTP Connector"|fl IgnoreSTARTTLS
- You should now be able to send messages via AuthSMTP without Exchange 2007 trying to negotiate a SSL/TLS connection.
Step Six (Optional)
- If you wish to change the default port that Exchange 2007 will connect to AuthSMTP on to one of the alternative ports please see Exchange 2007 - Alternative Port .
