Email, as a highly effective and universally used form of online communication, is vulnerable to manipulation by unscrupulous advertisers, criminals and hackers. Phishing, Malware and spam are commonly distributed to unsuspecting users by email. Spam email (unsolicited bulk commercial email) comprises over 80% of all email in the world today.
Spam Email - also known as junk email, involves nearly identical messages sent to numerous recipients by email. A common synonym for spam is unsolicited bulk email. The email is unsolicited and sent in bulk to hundreds of email addresses, frustrating and annoying email users.
Malware - viruses, worms, Trojan horses etc, designed to infiltrate or damage a computer system.
Phishing - criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and financial information (credit card details, account numbers) by masquerading as a trustworthy entity in an electronic communication.
ITNT Sentinal Anti-Spam is designed to protect your organisation from emails containing spam, malware (viruses) and phishing. These emails can flood organisations’ networks and cause major disruptions, in addition to the irritation of receiving hundreds of emails that have nothing to do with your day-to-day business dealings. Our anti-spam solution will save your organisation a considerable amount of bandwidth by ensuring that only legitimate email is delivered. All Spam is quarantined and blocked from being delivered to your corporate networks.
Sentinal Anti-Spam includes the following:
Most of the spam scanning is done with the help of SpamAssassin:
All emails classified as spam are stored in a quarantine section on the server for 60 days. An administrator has rights to release these if necessary. All data is stored in a SQL database for ease of reporting and statistical analysis.
ITNT offers a mail spooling service for hosts that do not have a full time connection or as a backup email solution in the event of your mail exchange server going offline. Emails coming to yourdomain.com will be queued in our mail server. If your mail server has an intermittent Internet connection then the mail server in your corporate LAN connects to our server to de-queue the mails. Common PC LAN GroupWare Applications like Novell GroupWise and Microsoft Exchange support ETRN for mail retrieval. The ETRN command is an extended Simple Mail Transfer Protocol (SMTP) e-mail de-queuing command that is issued to an e-mail host for Internet e-mail retrieval. Otherwise, our server will automatically send all queued mail to your server when it becomes available.
To ensure that your e-mail is free from viruses and spam, we protect your mailbox with anti-spam and anti-virus software. You can therefore receive e-mails without having to worry about downloading a computer virus or have your staff members receiving unwanted spam.
