Hello There,
Our email server is QMail on Linux. Since our mail boxes were getting filled with SPAM Messages, we decided to configure a SPAM detection server to receive all the mails sent to my domains. This server will check the mails for SPAM and will forward all the clean messages to my QMail server. This works fine but somehow my QMail is still receiving SPAM messages directly. I am sure that the MX records of my domains ponts to the SPAM Control server only. Still we are getting SPAMs directly delivered to my QMail server. I understand that I can restrict my QMail server to receive mails ONLY from the SPAM Control server so that only messages cleaned by the SPAM control server is delivered to my inbox. Can somebody please tell me how to I modify my QMail server settings to restrict the server to receive mails ONLY from one single IP, that is of the SPAM Control Server. Also please note that the Qmail server is also running FTP server which we occassionally use for file transfers.
Please help me.
Regards
FSS
