I get 3-400 messages an hour, like this in the postfix mail Queue, that gets bigger and bigger. How can I stop this ???
all the queue content is NOT from our users…

What you’d need to do is review the email headers in order to discover where the email is coming from.
It’s possible that a user on your server has an infected computer that is sending spam, for example. Or maybe someone’s password was compromised.
It’s also possible that someone broke into a website on your server, and is sending spam through that.
It should be possible to get some clues as to how the messages are being send by looking at the headers of the emails you’re seeing in your queue.
I ended up deleting the site. A script was causing the relay and spamming
Thanks for the help
