 Unsolicited email, or SPAM is becoming an increasingly big problem amongst internet users, and this can cause much grief to people who use email a lot. Currently, a solid 80% of the email that traverses the internet is unsolicited, consuming internet bandwidth, and wasting user time as email is sorted to find desired messages. Unfortunately, the people who generate the spam messages try to keep on top of administrator’s best efforts to prevent it from reaching the end user. Such tricks include adding random text, or common phrases to the spam email to make the mail look more legitimate, and more often the spam part of the message is inserted into an image attachment.

Rheel Electronics is dedicated to providing the best service to its customers, and this includes maintaining the quality of mail through the network. In response to the growing negative effect of spam, Rheel has developed a Web Appliance that sits in between the internet and the email system. This email gateway monitors all incoming and outgoing email through the Rheel email systems, and prevents email which is spam from getting through. The system also has an adaptation scheme that changes the filtering system as the spam encountered changes form, in an attempt to evade the filters, meaning that even the most cutting edge spam is caught. In addition to this, the email gateway checks mail for viruses, protect users from phishing schemes, and hidden exploits in email.

At the end of the day, this simply means that you, the end user, receive significantly less spam email (if any), and no email threats such as viruses and obfuscated web links make it through. This requires no configuration on your behalf, and comes as part of any ISP service provided by Rheel. If an email is blocked by a content filter, the user receives an email with instructions to contact somebody at Rheel to assist in retrieving the message if it is known to be safe. Otherwise, the Gatekeeper system self-updates and adapts the legitimate email that you, the user is sending whilst performing an outstanding job of keeping your mail free of unsolicited and dangerous email.

Some interesting statistics |

Currently the Gatekeeper processes around 25 000 emails a day, of which more than 20 000 are spam (and blocked). In the year past, the percentage of spam which was email has risen some 20%, to nearly 90%. Many hosting companies with spam protection have no method of stopping spam with the message in an image. Rheel’s Gatekeeper uses Optical Character Recognition (OCR) to decode these emails and check for spam.
