It is a well-established fact that 99% of the emails received over internet are either spam or contained viruses and such emails can be dropped at the first entry point of the Network. Thus, the first level in the proposed architecture has been taken as an email gateway which is equipped with antivirus and anti-spam software. Spam assassion is an open source freeware software for filtering of the spam emails. Perl based spamassassion id to CPU and Memory hungry for heavily loaded server thus this new arrangement would then overcome the Problem of slow Email access for users by detaching spamassassion from email repository servers. The second level of the servers with email repositories for users all the email servers used in this implementation would be Linux X86 servers. Virtualization technique pre- sents a software interface to virtual machines that is similar but not identical to that of the underlying hardware. First level is implement- ed in Virtual machine. So as to provide scalability, portability, migration and vendor independent. Keywords: Spam; Virus; Internet Protocol; Multilayer Filtering. 1. Introduction As computing becomes pervasive, people increasingly rely over the Internet. Now, the Internet is a preferred source to access online services such as E-mail services, e-banking, e-government, etc. User mails require a strong security mechanism from viruses and spam detection [1, 2]. Security is a major issue in internet based E-mail access service system. There are various internet threats which affect the security system of internet and increase risk for receiving bulk mail resources over highly secured net- work. Most of the spam and virus detection system relies on single layer filtering. Single-layer filtering is the traditional security process that re- quires antivirus and anti-spam software installation on server. Single layer filtering is vulnerable to detect spam because it re- quires lot of time to process mails on single server. For applica- tions that require greater security, it may be advisable to imple- ment more complex systems, such as multi-level anti spam, antivi- rus email setup [3]. In a two-level filtering system, incoming mails are processed at first level for filtering and scanning and processed mails are then forwarded to the second level mail server. The management of antivirus, anti spam and its supporting software complexities are handled by the centralized server configurations. Keeping the email-setup secure and containing clean mails in user’s inbox, while receiving mails from different domains, over Internet is a challenging task. The challenges start from filtering useful mails from all received mails which are received at first level (server level) to reduce the processing time of the second server, across the Internet is the most simplified way and without posing any potential threat to the networked resources. This paper has addressed the security issues involved in the email- setup of the organization accessible from the Internet. It allows users to access their mails present in their respective inboxes which are guarantees to contain monthly urgent emails. The above discussion underlines the need for Multilevel Email-setup for highly trusted network. To do so in the present work an Email- setup that is both secure and highly usable has been designed us- ing multiple levels. An email setup has been designed using multi- level scheme using Virtual Machines for better resource utilization and LDAP Server for managing information’s [4]. Fig. 1 shows the spam detection process of proposed architecture. Fig. 1: Spam Detection Process of Proposed System. 2. Existing system architecture It would not be a secure way for most of the email setup to simply use antivirus and anti spam software for spam and virus detection
