Features:

Web Based Administration
MailScan Administration Console can be accessed using a browser, to enable Remote Administration of the application. Using the web interface you can perform tasks like Gateway Configuration, User and Mail Restrictions, Mail Authentication, plugging vulnerabilities in Internet explorer to protect Mail Clients like Outlook Express which use IE plug-ins for displaying web pages, compression control, RBL checks, sending messages and notifications and accessing logs and detailed reports.

Blocks Spamming and Phishing
MailScan stops Spamming and Phishing using a combination of highly powerful technologies like,

• Non Intrusive Learning Patterns (NILP)
  This is a revolutionary technology from MicroWorld that works on the principles of Artificial Intelligence to create an adaptive, self-learning mechanism in Spam and Phishing Control.
  It is an advanced Bayesian Filtering method that can analyze each mail according to the Behavioral Patterns of the user and can take an informed decision there after. Unlike regular Bayesian filters, this system doesn't need to be trained, has the capability to learn on its own and incorporates regular research feeds from the MicroWorld Server.
  
• Real-time Black List (RBL)
  RBL is a DNS Server that lists IP Addresses of known Spam sending machines. If the contacting IP is found to be in one of the blacklisted categories, the connection is terminated.
• SURBL Check
  Unlike normal RBLs, SURBL Check works by scanning for the presence of names or URLs of Spam websites in the message body.
• General Header Tests
  MailScan checks the validity of all the headers in the mail and if any of the headers are found to be invalid, the mail will be considered as Spam.
  MX/A DNS Record Verification
  The domain part of the email address in the "MAIL FROM" SMTP command is checked to see if it has a DNS MX (Mail Server) and/or A (IP) record as it is typical of spammers to use non-existent domains in their emails.
• Reverse DNS
  A reverse DNS check is performed to see if the connecting IP resolves to a valid domain name before accepting or rejecting the email.
• X-Spam Rules Check
  X-Spam Rules are Rules that describe certain characteristics of a mail and they are matched against the mail header, body and attachment to generate a score for each mail. If the score crosses a threshold value, then the mail is considered a Spam.
• Sender Policy Framework (SPF)
  Sender Policy Framework is a world standard that helps to prevent forgery of sender address and is a powerful mechanism to stop Phishing mails.
• Auto Updates for Spam Detection
  The system updates the Bayesian Spam Database with probable phrases and words.
• Blocks Image Spam
  MailScan uses powerful technologies to filter out image spam.

Auto Updates for Spam Detection
The system updates the NILP Spam Database with probable phrases and words.

Autogenerated Spam Whitelist
When a local user sends a mail to an email address, the system automatically adds that ID to the Spam Whitelist.

Real-Time Virus Scanning
Scans e-mails for all types of malware in Real-Time including all inbound and outbound, SMTP and POP3 mail traffic at the Mail Gateway itself.

Scanner Administration
This feature allows you can add local primary domain, configure settings for auto-download of updates and plug Internet Explorer vulnerabilities that allow Viruses to enter your system. You can also block or allow specific types of e-mail attachments that are prone to virus infections.

Heuristic Scanning
Sophisticated Heuristic Scanning to prevent newer Viruses, mutant variants and hidden malice in a proactive and pre-emptive manner.

Real-Time Content Scanning
All incoming and outgoing messages are scanned in Real-Time for offensive words, Adult Content and expressions using Security Policies.

Heuristic Scanning
Sophisticated Heuristic Scanning to prevent newer Viruses, mutant variants and hidden malice in a proactive and pre-emptive manner.

LDAP Authenticated Web Administration
MailScan is powered with LDAP Authenticated Web Administration.

TCP Connections
This option shows all TCP/UDP connections in the system, like Processes, Protocol, Local Address, Remote Address, Data Sent, Data Received and more

POP3 Downloader Module
MailScan acts as a SMTP/POP3 e-mail gateway that allows users to download messages from their Internet POP3 mailboxes to local e-mail folders.

This feature can,

• apply size restrictions while downloading mails.
  
• wildcard account download is supported. A single account collects mails for the entire domain and then distributes to individual accounts.
  
• duplicate mails are deleted at the Server itself.
  
• smallest message is downloaded first.
  
• configurable to schedule download of mails at regular intervals.

Attachment Filtering
Extensive options to block certain attachments like EXE, COM, CHM or BAT from being sent or received.

S/MIME Check of Messages
Checks S/MIME Digital Signatures and warn the user if the content of the mail is changed or tampered with.

Mail Traffic Management with Scan Control
Provides an option to define a selected list of users, whose mails need to be scanned. You can also block certain users from sending or receiving emails.

Attachment & eMail Archiving
Customizable options to archive e-mails and attachments flowing in and out of the system. This also helps in comprehensive email auditing.

Compression and Decompression
Oversized files are compressed using standard file compressors with options for automatic decompression. MailScan can be configured to create 'EXE' files or self-extracting zip files that are automatically decompressed at the recipient's machine.

Mail parking and Mail delay
This feature enables you to delay Outbound Mails. You can specify the threshold size of e-mails, and once it is crossed it will be parked for a specific duration.

Clustering
This feature is greatly useful to those ISPs or Servers that handle a large number of mails regularly. Clustering enables you to distribute mails to multiple computers for scanning and thus provides load balancing for the Mail Servers for faster processing.

Relay Control
It provides Relay Control using IP-blocks to ensure that unauthorized IP addresses are blocked from sending mails through the Mail Server.

ETRN Support
ETRN is an extension to the SMTP mail delivery protocol that allows an SMTP server to request for emails of a specific domain, from another Server. This helps protect Mail Servers that do not have a dedicated connection to the Internet.

TCP Connections
This option shows all TCP/UDP connections in the system, like Processes, Protocol, Local Address, Remote Address and Status.

Customized Disclaimers
Easy to use options to add Customized Disclaimers all external and internal emails

Automatic Updates
Automatically updates new Virus Signatures and antidotes as the AntiVirus database of MailScan is updated every hour.

Logs and Extensive Reports
MailScan registers its activities into logs and generates graphical and non-graphical reports on demand, for review and analysis.

24x7 Free Technical Support
