Hi list, and thanks for reading. I'm looking for a way to encourage users to properly set their MAIL FROM fields, in order to allow them to relay through my server.
I already have IP based, and SMTP AUTH based authentication, but now I want all my users to behave "right". The problem is that here in Argentina its becoming very popular some attack using bounces, and I dont want my server to be banned. I have about 30 domains, so I would need something like checking if the domain part of the email its on the "locals" file. Is there any patch for qmail-smtpd that could help me? Thanks in advance!
