I have a vps and host a number of websites on it.
I'm trying to get this pci compliant and something that has been thrown up is:
" Description: MTA Open Mail Relaying Allowed Synoposis: An open SMTP relay is running on this port. Impact: The remote SMTP server appears to allow mail relaying"
It says I need to:
Reconfigure your SMTP server so that it cannot be used as a relay any more
How do I do this and will it effect the users who access their mail via outlook etc?
Thanks in advance.
