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 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

Hi, I'd love to help you with your postfix situation. I'd have a look at your system logs and give things a quick once over to make sure the issue is in fact a loose configuration and if it is I'd set postfix to only allow mail to be sent by local applications. If there's any other reason for mail being sent out I'll let you know. At them I'll provide you with a brief document explaining what I found & steps taken. Feel free to get in touch if you have any questions. All the best, Chris

I'm an experienced linux administrator with many servers on my watch around the world... I have advanced knowledge of postfix configuration and over a decade of experience on niche mail server setup. Of course you need to understand that if you have a form vulnerable to attacks and you configure a user to send emails though that form, postfix ain't your problem... I'm available for any queries you may have...
