Charles, Just for clarification, and remember, I am very new at all of this.
Postfix is requiring SASL Authentication. I have not listed any user names or passwords anywhere except in Apple Open Directory as User "Short Names" for use with login to network resources. Postfix seems to reference these user "Short Names" in OD and the user's password, also from within OD, when performing SASL Authentication. These same user "Short Names" are also seen as valid Email addresses at my domain when receiving email. This information is not listed anywhere else in my configuration. For that reason, I am asking if Postfix can't also see the User "Short Names" as Email addresses when performing "reject_sender_login_mismatch" under "smtpd_sender_restrictions". My whole goal is to avoid creating and updating another separate list of Email Addresses and User Names for "smtpd_sender_login_maps".

What do you mean by 'pull their email addresses'? If you mean that you have assigned multiple email addresses for each user in some attribute in OD, and you want 'sender_login_mismatch' to only allow the user to send if they are sending from one of these multiple email addresses, I'm not sure how you would do that, but I'm trying to more precisely define what it is you are trying to do... -- Best regards, Charles
