Microsoft Exchange 2010 - SSL/TLS
- These instructions assume you have already setup your AuthSMTP send connector in Exchange 2010 using the instructions on the Exchange 2010 setup page .
- Microsoft Exchange 2010 has a feature called 'Opportunistic TLS' which is enabled by default upon installation, this feature means Exchange 2010 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 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 2010.
- 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 2010 trying to negotiate a SSL/TLS connection.
Step Seven (Optional)
- If you wish to change the default port that Exchange 2010 will connect to AuthSMTP on to one of the alternative ports please see Exchange 2010 - Alternative Port .
