Detailed information for the notes.ini Keyword: 

SMTPVerifyAuthenticatedSender


Short Description:  Specifies whether the SMTP server requires mail sent during an authenticated session to be from the Internet address of the authenticated user.

Description:
The SMTPVerifyAuthenticatedSender= NOTES.INI setting designates whether mail that is sent during an authenticated SMTP session must be from the Internet address of the authenticated users. The intent is to verify that the user is not attempting to spoof the "From" field. This feature is most useful when a Domino SMTP server is configured to enforce authentication, but that is not a requirement.

SMTPVerifyAuthenticatedSender has multiple values.


Description: Specifies whether the SMTP server requires mail sent during an authenticated session to be from the Internet address of the authenticated user.


    0 - Do not require the sender to use their Internet address

    1- Require the Sender, or From, if Sender header does not exist, to match the Internet address of the authenticated server.

    2 - Require the RFC822 From header to match the Internet address of the authenticated user. Sender is not checked, just From is checked


This setting does not affect the Router, nor does it affect messages that are not submitted via SMTP.

The SMTPVerifyAuthenticatedSender setting does not work when SMTPTranslateAddresses is configured. Mail is rejected if addresses are translated because the match fails.

The features can only be used with single-address entries in the From or Sender field.
