mail from global bad sender still getting through
For a while now, myself and some of my users have been getting emails containing suspicious files.
Always seeming like they come from the same email adress, but behind the screens they originate from the most diverse email adresses.
So blocking the sender is out of the question.
Is there a way to block emails contaning certain data? (strings?)
When looking into the senders IP adress this is listed among the Global Bad Senders, and Global bad senders are configured as Reject SMTP connection.
However the e-mail still gets through... How do I get this resolved?
