SpamAssassin Heuristic Analysis New in 7.0!
SpamAssassin combines the most effective anti-spam technologies into
one powerful solution that accurately determines what messages are or
are not spam. It uses a comprehensive list of rules and checks to score
messages based on the likelihood that they are spam. This filtering is
completely automated, and spam-scoring thresholds are customizable. It
also integrates directly with the Bayesian filters and offers many
additional features, such as complete spam message reporting, header
reporting and much more. Challenge-Response Mechanism New in 7.0!
The optional challenge-response mechanism is the last line of defense
in anti spam security. It is the most foolproof method to ensure that
your organization is spam free. If the SpamAssassin and Bayesian
filters cannot definitively prove that a message is or is not spam, a
challenge message is sent to the message originator. The originator is
presented with an imbedded link in the message. Once they click on this
link and enter a password, their message and all of their future
messages will be allowed. This mechanism ensures that messages are
being sent from a "real" person, and provides the highest level of spam
protection. HTML Filtering New in 7.0!
Accurately filter 99% of all html spam messages using these
sophisticated rule sets. A common spamming technique is to send
messages in all HTML format, which prevents most message body scans
from reading data correctly. These filters ensure that these messages
are examined and spam is identified. HTML filters are updated with new
VisNetic Mail Server software releases to reflect new HTML spam
tendencies. Bayesian filtering statistically calculates the probability that each inbound message is spam. The Bayesian filter updates automatically via a spam database that is uploaded to the server. Bayesian filtering is cutting-edge anti-spam technology capable of eliminating nearly 100% of spam with little to no occurrence of false-positives (legitimate email incorrectly labeled as spam). Because it is measuring probabilities, the Bayesian approach considers all the content in an email, both good and bad. Email containing a high number of bad elements with few good elements achieves a high probability and is automatically deleted, rejected or placed in the recipient's Spam folder. Email containing a high number of good elements with few bad elements is accepted. This ensures that an otherwise innocent email that happens to include the word "buy" is not going to get tagged as spam. VisNetic Mail Server has a very powerful and intuitive email content filtering tool. Filter incoming and outgoing emails based on a number of variables including, subject, sender and/or recipient, key words in the text, and more, through a user-friendly interface. Set the content filter to forward, delete, reject or allow messages. Programs and DLL's can also be executed. You can even create a filter for attachments using layman's logic. VisNetic Mail Server supports several bypass files. If a named file exists with certain content, or if a message contains a recipient or sender listed in the bypass file, the content filters or anti spam filters will be ignored. The file can contain email addresses and domains, IP addresses, masks each per line. All filter files support header, attachment, body, IP, as well as other conditions using RegEx (like 'contains'). Further enable protection by using SPAM email blocker services that incorporate a black list of known spammers, to effectively block the relaying of SPAM through VisNetic Mail Server. White and Black lists allow you to define which email addresses are permitted or denied. Lists can be administered by users or administrators via VisNetic WebMail, the Jabber Instant Messaging Client, and addresses can be added via the Challenge-Response Mechanism - e.g., if a message originator verifies himself as a legitimate source he or she can automatically be added to the white list. VisNetic GroupWare Support New in 7.0!
VisNetic Mail Server 7.0 includes support for VisNetic GroupWare.
GroupWare is collaboration software that integrates directly with
VisNetic Mail Server, Outlook 2000/2002/XP/2003, VisNetic WebMail and
any other application via an open API--providing web-based access to
shared calendars, appointments and address books. This is an out-of-the
box solution that enables easy access to shared address books,
appointments, invitations, automated reminders, and more. VisNetic
GroupWare is the most comprehensive, cost-effective shared calendaring
and address book solution available. Host your own instant messaging server in-house without additional software or installations. Included in VisNetic Mail Server is an Instant Messaging Server that allows you to communicate internally and externally via an encrypted, SSL connection. This method of communication will greatly increase productivity, allowing employees and/or customers to correspond while multitasking, see who is Online/available without leaving your desk, and much more. Also use IM to access pending messages (designated by spam filters) and calendaring information. VisNetic Mail Server can connect to any ODBC compliant database (e.g. SQL, MySQL, Access). This simplifies setup of user accounts, mailing lists, etc., as existing lists can be imported into VisNetic Mail Server. Support for ODBC connections also allows for centralized management of user data. Instead of creating and maintaining user data in multiple applications, administrators can manage and backup the data in one place, accessing it from VisNetic Mail Server with ease. With Multiple Domain Support, a single VisNetic Mail Server can handle several unique domains (or different addresses). If a company has several identities, all mail can be handled through one server. By reducing the administration burden inherent in running multiple email servers, all email tasks can be made more efficient, and a company can apply consistent routing and filtering rules across all of its accounts. VisNetic Mail Server offers support for POP3, SMTP, IMAP, LDAP, HTTP, and WAP (available through VisNetic WebMail). Account holders can check their mail using email software on desktop computers, laptops, cell phones, and PDAs. An email message can be sent to a single address and automatically distributed to several different recipients. Multiple mailing lists, of various sizes, can be created by the administrator. VisNetic Mail Server's List Server allows for the administration of a mailing list via email commands. The List Server also supports moderated lists. A company can take advantage of lists to keep several account holders in contact with one another and quickly contact large groups with critical information. VisNetic Mail Server supports remote administration options for mail administrators. The Remote GUI is a user-interface that interacts with Mail Server over SSL sockets while providing a familiar interface to enact changes and updates to VisNetic Mail Server from a computer other than the server itself. The Web Administration utility gives an administrator complete control of the mail server through a secure, browser connection. Included standard with any VisNetic Mail Server license, VisNetic WebMail is a web based email client that can be accessed through any Internet browser on a computer with Internet access. . Access email accounts, shared calendars (using VisNetic GroupMail), pending messages (designated by spam filters), and much more via your web browser. A built-in WAP engine allows VisNetic WebMail to deliver messages to PDAs and cell phones as well. VisNetic WebMail supports secure (https) connections by default, to better protect all email activity. VisNetic Mail Server's MultiPOP account feature makes it possible to collect email messages from any number of POP accounts on multiple servers and deposit them directly into the VisNetic Mail Server user's mailbox. VisNetic Mail Server eases administration efforts by supporting the import of a pre-existing Windows NT user database. VisNetic Mail Server will use the NT database to create user accounts. API DLL support allows programmers to develop programs and DLL's that can interface with the VisNetic Mail Server directly. This gives programmers the freedom to create programs that allow for direct access to the mail server to manipulate and create domains, users, mailing lists, and more. VisNetic Mail Server can be set up to automatically mail a user-defined message anytime an email is received to the specified users account. Particularly useful for employees who spend a great deal of time out of the office, or during vacations. Passwords are secure, even when logging in across the Internet, because VisNetic Mail Server is able to encrypt this data. VMS supports public IMAP Folders. Public folders are folders available to IMAP users, in addition to their private IMAP folders. When an IMAP user accesses their folder list, they will see both their private and shared folders; mail directories may be shared, while limiting each user to the mail server associated with their individual logon credentials. Route an IMAP message via SMTP to any folder (even shared folders), based on specified criteria. This feature allows administrators to maintain rules settings on the server, as users check email from various clients. Export content filter configurations from Mail Server to Mail Server to eliminate redundancy in recreating complex configurations - great for organizations running multiple mail servers. In business, it is critical to be able to determine when events happen. VisNetic Mail Server performs time synchronization using NTP (network time protocol), the most widely accepted method for maintaining time across a network. NTP is not based on the principle of synchronizing machines with each other, but with having all machines as close as possible to UTC (universal correct time). This feature allows users to retrieve contents of specified directories. For example, you can specify the path to the VMS log directory, send an email to the catalog, and have VMS send the log to you. Control access to public and shared folders using Access Control Lists; specify rights for each mailbox and identifier (user). TLS (Transport Layer Security)/SSL (Secure Sockets Layer) Support allows VisNetic Mail Server to pass email messages in an encrypted format between servers, and from secure clients (i.e.; any TLS/SSL enabled client; POP3, IMAP, LDAP, etc., like Outlook) to servers. By using these security protocols, a company with multiple offices can create a secure email pipeline with VisNetic Mail Servers at both ends of the connection and with secure clients for employees. Encrypted messages are safe from hackers or information thieves. For email sent to unknown mail servers on the Internet, VisNetic Mail Server will always attempt a secure connection before sending. VisNetic Mail Server is set up to use TLS as its primary encryption method when communicating with another TLS enabled mail server. If TLS is unavailable, VisNetic Mail Server will automatically use SSL. VisNetic AntiVirus Protection Plug-in for VisNetic Mail Server places comprehensive email antivirus protection directly on the mail server. By placing antivirus protection on the email gateway, an entire network is protected from inbound email born viruses. Powered by Kaspersky Labs, VisNetic AntiVirus Protection Plug-in is powered by leading edge technology and uses the latest antivirus protection information available. Administrators can configure VisNetic Mail Server to check for unsuccessful attempts to deliver emails to unknown users by external or local non-existing users. If the number of attempts in a session exceeds the number specified by the Admin, the IP address of the sender will be remembered for that period and no access from that IP address will be allowed within the period. VisNetic Mail Server allows email clients to authenticate before sending and receiving email. By using authentication methods, VisNetic Mail Server can further protect itself from being used as a relay point. Users must identify themselves to the server and be approved to use the mail server. VisNetic Mail Server has a very powerful and intuitive email content filtering tool. Filter incoming and outgoing emails based on a number of variables including, subject, sender and/or recipient, key words in the text, and more, through a user-friendly interface. Set the content filter to forward, delete, reject or allow messages. Programs and DLL's can also be executed. You can even create a filter for attachments using layman's logic. Restrictions can be placed on mailboxes according to overall size, maximum number of megabytes sent per day, even maximum number of messages sent per day. These restrictions help administrators control bandwidth across all accounts. VisNetic Mail Server supports several bypass files. If a named file exists with certain content, or if a message contains a recipient or sender listed in the bypass file, the content filters or anti spam filters will be ignored. The file can contain email addresses and domains, IP addresses, masks each per line. VisNetic Mail Server will recognize and utilize multiple processors installed on the server computer. This results in optimum performance when the server experiences heavy traffic. By taking advantage of all the available processing power, VisNetic Mail Server is able to handle more email faster than its competitors. Administrators can configure VisNetic Mail Server to automatically backup critical system information, such as user account data, server configurations, and license data, and will store the backup file separate from the mail server. Should anything happen to VisNetic Mail Server or the computer it is running on, restoration is made easier with the backup file safely stored elsewhere. It is also possible to run a manual backup at any time. VisNetic Mail Server's Real Time Monitoring provides SMTP/POP3/IMAP Statistics on Uptime, Total Connections, Messages Sent/Received, Message Failures due to Viruses, Static Filters and Content Filter Configurations. This information is displayed graphically to administrators, for "at-a-glance" stats on the performance. Active SMTP and POP3 sessions are also displayed, along with session histories. VisNetic Mail Server's watchdog feature ensures that SMTP, POP3, IMAP services (or an ODBC source - Pro version only) are always running. If a service stops for any reason, watchdog will automatically restart it, based on the set time interval indicated by the Administrator. Administrators can also request to be notified when a service is down for more than "x" minutes, and when the server is back online. By automatically monitoring these delivery protocols, VisNetic Mail Server is better equipped to keep itself running smoothly, and delivering email. The Disk Space monitor will track the available hard disk space on the server computer. When the free space reaches a user specified level, the Disk Space Monitor will trigger VisNetic Mail Server to send notification to the server administrator. By actively tracking the disk space, VisNetic Mail Server protects against failure caused by a lack of memory. ATRN allows a user to reliably run a mail server when using a dynamic IP address. When using ATRN, messages are immediately downloaded to the requesting host. DUN support allows VisNetic Mail Server to run even when it is not connected to a permanent Internet connection. Administrators can set connection times and the mail server can automatically trigger the Internet connection, complete its mail tasks, and shut the connection down again. Separate logs can be produced for each individual service in VisNetic Mail Server (including POP3, SMTP, IMAP, and Control and HTTP services). As well, VisNetic Mail Server can produce logs showing activity by users, including the size and number of messages sent and received by each account. . |
