MOM Rule Name

The Send connector requires TLS before the MailFrom command can be run. However, the connector is not configured to accept TLS. Check the connector's authentication setting and the remote server's EHLO response.

This Error event indicates the specified Send connector must use Transport Layer Security (TLS) for all messages that are sent to the remote server. However, the remote server is not configured to accept TLS.

A Send connector requires TLS for all sent messages when the RequireTLS parameter on the Set-SendConnector cmdlet in the Exchange Management Shell is set to the value $true. The default value is $false.

If the remote server is configured to accept TLS, the remote server displays 250-STARTTLS in the response to the EHLO command. If the remote server does not display 250-STARTTLS in the response to the EHLO command, the remote server is not configured to accept TLS.

To resolve this error, do one or more of the following:

  • Configure the remote server to accept TLS. If the remote server is a Microsoft Exchange Server 2007 Hub Transport server or Edge Transport server, the AuthMechanism parameter of the relevant Receive connector must contain the value TLS.

    You can verify that the remote server accepts TLS by using Telnet on port 25 to connect to the remote server, and observing 250-STARTTLS in the response to the EHLO command.

  • Configure the specified Send connector not to require TLS by setting the RequireTLS parameter on the Set-SendConnector cmdlet in the Exchange Management Shell to the value $false.
