MailScan 6.1 for VOPMail is the world's first "Real-Time" e-mail scanner for the VOPMail Mail Server. This server is published by Vircom Inc. MailScan for VOPMail acts like a Content-Security and Anti-Virus Software for your Corporate VOPMail Mail Server. It scans and cleans e-mails that: A) Flow between all the local users. B) Go from your VOPMail Mail Server to the Internet. C) Come into your VOPMail Mail Server from the Internet (either via SMTP or POP3). MailScan is the *only* product available in the world that transparently works on both SMTP and POP3 traffic. It has the world's first e-mail Content-Security and Anti-Virus feature that analyzes e-mails on a real time basis *before* they are delivered to your clients or servers. Both SMTP and POP3 are supported. Technically, a new layer the MicroWorld Winsock Layer (MWL) is introduced between the default WinSock2 and the applications. This layer is responsible for analyzing the traffic that flows between VOPMail and the Internet or your applications. Anti-Virus and Content-Checking are only some of the benefits offered by MailScan. It also has a Generic Attachment Analyzer, automatic compression/decompression feature, a comprehensive Notification engine and many features not found in other products. MailScan uses the eScan Content-Security and Anti-Virus feature to scan all e-mail attachments. Incoming and outgoing e-mails are scanned and cleaned of viruses and their contents checked, before your actual e-mail server processes them. All the 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 emails, Multipart-Mixed and Multipart-Digest types. USPs offered by MailScan are: 1.No port settings or changes need to be done inside VOPMail. / Dedicated gateway machine not needed for using MailScan. 2. MailScan works along with VOPMail.
