I have my Exchange server setup to use Postfix as it's outbound SMTP
relay.
I have been tasked with the following and am not sure how to use
Postfix to accomplish it:
1.) Block certain users (listed within a text file or postfix db list)
within the company from sending emails with an attachment.
2.) Instantly deny the email from going out and sending back an SMTP
(or similar) warning/message to the user that outbound attachments are
not allowed.
Has anyone setup something like this or can point me in the right
direction?
