I want to setup a Server-Client Architecture for Internet/Emails to stop the VIRUSES and SPAM.
Means all the Emails through our POP should be scanned on the Local Server and then relay to the staff and same should be with SMTP.
Our Structure is
|| ISP Router > Hub > PCs(approx 40)
i want to put a Server in between this architecture so that i would be able to Stop SPAM & Viruses on the Server.
Please advise, How to do this completely? which software we should use on server?
Thanks & Regards
