I have a server running Postfix on CentOS 6.5 and I think the permissions need tightening up to prevent the mail server sending messages other than from domains on the server
I need someone familiar with Postfix who can set it up so forms on the web server, mail etc still work but the mail server can't be used by other people to send spam.
Hello from Poland. Lots of sysadmin experience here. I'm able to help you with the postfix issue. Just let me know in the chat whenever you might need me. Thank you.

Hello Sir, as you say that mails are sending by using your server then it means your server may be infected with malwares so I need to scan your server. Thanks
