Only accept mail from virus/spam service

Hello,

For our business customers we have a server with FreeBSD 6.2 and Plesk 8.1.

All the user on this machine have a spam/virus service, this is provided by Cleanport (we first delever the mail true MX records to Cleanport, a special server that checks the mail on spam and virus and send the clean mails to our server)

At this moment some people delever spam mails direct on the IP Address from the server, so the mails don't come true Cleanport. At this moment we get a lot of spam.

Because every customer on this server have a cleanport service we want te config Qmail that qmail only accept mail from the cleanport ip addresses. Not from any other address (except localhost).

Is this posible? and how can we config this in qmail?

Best Regards,

Ron

Do it with firewall rules. Just restrict incoming traffic on port 25 from them, and tell your users to use SSL SMTP (port 465) .
