VisNetic MailServer 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 MailServer is able to handle more email faster than its competitors.

Administrators can configure VisNetic MailServer 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 MailServer 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.

The watchdog on VisNetic MailServer ensures that SMTP, POP3, and IMAP services are always running. If, for any reason, any of the services stop, the watchdog feature will restart the service automatically. Administrators can set the time interval at which the watchdog should start downed services. By automatically monitoring these delivery protocols, VisNetic MailServer 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 MailServer to send notification to the server administrator. By actively tracking the disk space, VisNetic MailServer 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 MailServer 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 MailServer (including POP3, SMTP, IMAP, and Control and HTTP services). As well, VisNetic MailServer can produce logs showing activity by users, including the size and number of messages sent and received by each account.

VisNetic MailServer'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.

TLS (Transport Layer Security)/SSL (Secure Sockets Layer) Support allows VisNetic MailServer to pass email messages in an encrypted format between servers. By using these security protocols, a company with multiple offices can create a secure email pipeline with VisNetic MailServers at both ends of the connection. Encrypted messages are safe from hackers or information thieves. For email sent to unknown mail servers on the Internet, VisNetic MailServer will always attempt a secure connection before sending. VisNetic MailServer is set up to use TLS as its primary encryption method when communicating with another TLS enabled mail server. If TLS is unavailable, VisNetic MailServer will automatically use SSL.

VisNetic AntiVirus Plug-in for VisNetic MailServer places comprehensive email virus protection directly on the mail server. By placing virus protection on the email gateway, an entire network is protected from inbound email born viruses. Powered by Kaspersky Labs, VisNetic AntiVirus Plug-in is powered by leading edge technology and uses the latest virus protection information available.

Administrators can configure VisNetic MailServer 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 the Period and no access from that IP address will be allowed within the period.

VisNetic MailServer allows email clients to authenticate before sending and recieving email. By using authentication methods, VisNetic MailServer 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.

This feature enables SPAM blocking services that incorporate a black list of known spammers to effectively block the relaying of SPAM through VisNetic MailServer.

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 MailServer can connect to any ODBC compliant database (e.g. SQL). This simplifies setup of user accounts, mailing lists, etc., as existing lists can be imported into VisNetic MailServer. 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 MailServer with ease.

With Multiple Domain Support, a single VisNetic MailServer 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 its accounts.

VisNetic MailServer 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.

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 MailServer supports remote administration options for mail administrators. The Remote GUI is a user-interface that interacts with MailServer over SSL sockets while providing a familiar interface to enact changes and updates to VisNetic MailServer 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 MailServer license, VisNetic WebMail is a web based email client that can be accessed through any Internet browser on a computer with Internet access. 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 MailServer'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 MailServer user's mailbox.

VisNetic MailServer eases administration efforts by supporting the import of a pre-existing Windows NT user database. VisNetic MailServer 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 MailServer 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.
