MailScan 4 for Microsoft Exchange Server, acts like a Content-Security and Anti-Virus Software between your Corporate Exchange Mail Server and the Internet. It has the world's first "real-time", e-mail Content-Security and Anti-Virus feature that analyzes e-mails before they are delivered to the clients or the servers on your network. Both SMTP and POP3 are supported. Technically, a new layer the MicroWorld WinSock Layer (MWL) is placed between the default WinSock2 and the applications. MWL analyzes traffic that flows between the Microsoft Exchange Server and the Internet. Besides providing Anti-Virus and Content-Scanning features, MailScan also has a Generic Attachment Analyzer, automatic compression/decompression feature, a comprehensive notification Engine, etc. MailScan uses the eScan Content-Security and Anti-Virus solution to scan all e-mails. Incoming and outgoing e-mails are scanned and cleaned and their contents checked before your e-mail server processes them. All MailScan processes are multi-threaded. This ensures that all e-mails are parallely processed. All types of attachments are handled by MailScan, including MIME and UUEncoded. Other types supported are: RFC822 attachments, Embedded e-mails, Multipart-Mixed and Multipart-Digest types. USPs of MailScan are: 1. No port settings or changes need to be done inside Microsoft Exchange Server. 2. Dedicated gateway machine not needed for using MailScan. 3. MailScan works along with MS Exchange on the same machine. 4. Unlike other products, you will NOT lose any of the SMTP functionality's given by MS Exchange. Support 24 X 7 FREE ONLINE SUPPORT
