mail server problem, need help urgent!!
I'm having this problem. I've disabled user nobody to send mail as to prevent spammers from relaying my mailserver to send mails out.
However, this action has made a lot of incoveniences to my clients as their CMS (forums and so) unable to send mail to newly registered users for verification purposes.
Is there any way to solve it or there are other options to stop spammers relaying our mailserver to send mail out without giving any troubles to my clients?
Thanks in advanced
