OUR PRODUCTS SYSTEM INTEGRATION    Softerprise All-in-one Email System Softerprise All-in-one Email system is a state-of-the-art groupware server allowing companies to collaborate via email, shared contacts, shared calendars and tasks.   FEATURES Secure mail Softerprise All-in-one Email System is a secure, high-performance, multi-domain, mail server working with all POP3 and IMAP desktop mail clients for Windows, Linux and Mac. Anti-virus protection Dual anti-virus control provides administrators with the ability to use more than one virus scanning products keeping all incoming and outgoing emails virus free. Anti-spam protection A combination of content-based SpamAssassin and sender-based anti-spam tools in our system significantly reduces the amount of unwanted email, helping to limit the legal hassles and security risks associated with spam.  Details of Anti-Spam protection 1. Directory Harvest Attack protection Directory Harvest Attacks abuse the design of the SMTP protocol. When one mail server attempts to deliver a message to another mail server, it first inquires whether the recipient address exists on the target mail server. If it exists, the target mail server sends a confirmation; if not, the server responds with negative answer. Spammers take advantage of this communication by submitting multiple requests with different combinations of first and last names. By harvesting valid responses, spammers get very precise list of valid email addresses suitable for future spamming. To fight directory harvest attacks, our Server monitors any unusual change in SMTP activity and once this attack is recognized, it applies several defensive techniques such as slowing down responses, cutting off connections and faking responses. 2. Spam Repellent Spam Repellent helps fight off spam zombies and viruses by delaying replies during the SMTP handshake. Since spam mailers and viruses are very impatient when it comes to SMTP communication, they don't wait if the replies from a target mail server are not timely, and simply move on to try another target. By injecting an artificial time delay of a couple of seconds into the SMTP handshake, our system may filter up to 60-70 percent of spam and viruses without ever receiving the messages for analysis. 3. SpamAssassin SpamAssassin is a powerful anti-spam engine integrated into Softerprise all-in-one mail server that identifies junk email. Combining several technologies, SpamAssassin ensures that bulk spam email is properly captured and legitimate email is reliably delivered. - Heuristic engine Using the heuristic engine in SpamAssassin, each email message is analyzed against multiple anti-spam rules and gives it a numerical rating based on which rules were matched. If the message rating exceeds the spam threshold, the message is marked as spam and then filtered according to the user's wishes. - Bayesian filter To further increase the success rate and tailor the spam filter to the individual needs of every company, MailServer allows WebMail users to easily train the Bayesian filter in SpamAssassin for every email message that is miscategorized. The Bayesian filter can also be trained by dragging and dropping email in or out of Server's Junk E-mail folder in any IMAP email client. SpamAssassin then compares incoming messages to spam messages reported by other users, and sees how similar they are to those reported messages. 4. Dual filtering policies Dual filtering policies give administrators the ability to tag messages with low spam score as spam and forward them to user's Junk Email Folders, whereas messages with really high spam score can be automatically discarded without ever reaching user's mailbox. Discarding emails with high spam scoring can help save hard drive space and reduce the amount of emails that endusers need to audit. 5. SURBL blocking Similar to RBLs, SURBL (Spam URI Realtime Block Lists) will block messages that contains URIs (usually Web sites) in the message body that links to known spam hosts. 6. Real time blacklist support Checks sender's IP address for each incoming SMTP connection. If the IP address is in the database of open-relay servers identified as spammers, the incoming email is refused. 7. Sender's domain verification Rejects emails when sender's email address is using an invalid or fake domain name. 8. Custom filtering by address, subject, content or size Can reject emails from notorious spammers not known to public blacklists. Allows for the creation of a custom blacklist. An efficient measure to fight against empty "From" fields in spam emails. 9. SMTP authorization by user name and password Requires users to authenticate before sending email through SMTP. 10. SMTP authorization by IP address Limits SMTP relay access to specified range of IP addresses. Relay access is usually allowed for users within local area networks (LAN). 11. "Sent email per hour" quota Limits number of emails that one user (IP address) can send within a specific time period. Significantly reduces the risk of mail server abuse if spammer has accidentally acquired trusted user access rights. 12. "Concurrent connection" limit Limits number of concurrent SMTP connections made from one IP address (one user). Protects mail server resources by limiting mail load. Prevents the use of specially designed spam programs that create multiple connections to increase the number of emails being sent to SMTP server. WebMail & WebMail Mini Two different web-based email clients, one with the look and feel of Microsoft Outlook and the other optimized for viewing email on PDA devices, provide users with both comfort and speed while working from most modern web browsers, including Internet Explorer and Firefox.  Details of WebMail System 1. Real groupware capabilities Just like a real desktop application, our WebMail lets users view and manage email, calendars, contacts, notes and tasks over both corporate LANs and the Internet. 2. Rapid responses Speed of access has been always an issue with webmail, so our WebMail takes a different approach from traditional solutions. It downloads only updated segments of a web page rather than downloading the entire page. With faster mail browsing, administrators can replace traditional email clients with webmail with less protest from users. 3. Automated message retrieval Our WebMail automatically checks for new messages without requiring the user to refresh the screen or click on any buttons. Even when a user leaves a WebMail window unattended, new incoming messages will pop-up in the inbox. 4. Public, private & shared Contacts Users can access and manage their private address book from webmail. Since contacts are centrally stored at the server, it has never been easier to share them with other users. Users can also subscribe to multiple public address books so that departments can share their self-managed directories with their entire organization. 5. Calendar and reminders Our WebMail hosts both private and shared calendars. From WebMail users can view other people's calendars or share their calendars with selected colleagues. Just like in Outlook, when an event or appointment is due, WebMail pops up an event reminder. Therefore no important event is ever missed, even when connected from a remote location. 6. Integrated advanced features Our WebMail integrates technologies and features to make working with webmail as productive as working with a software email browser. 7. Out-of-office reply The smart auto-response filter will automatically send your out-of-office reply message while you are gone, and not duplicate the message to addressees that send you more than one email. 8. Free/busy time lookup Schedule meetings with colleagues and check their availability from WebMail. Drag & drop for email and calendar events Moving email messages between folders has never been easier. Just drag the message and move it to another folder. 9. Spell checker with customizable dictionary No more worries about a misspelled word or two. The integrated spell checker allows you to add your own words or expressions in addition to its extensive dictionary. 10. Send & receive attachments All incoming pictures can be directly displayed in the email preview window. Up to 10 attachments can be sent at a time. 11. "Sent email per hour" quota Limits number of emails that one user (IP address) can send within a specific time period. Significantly reduces the risk of mail server abuse if spammer has accidentally acquired trusted user access rights. 12. Custom signature Attach your pre-defined signature to every email you send out. Easy administration Administrators can easily add/remove/modify user accounts, email addresses and aliases through a web interface. User quota could be easily applied with a few clicks. Backup of emails and system could be performed in a scheduled maner. Scalability Softerprise All-in-one MailServer is a scalable messaging server that can support anywhere from 20 users, in a small local area network, to several hundred users running from a single server.
