Clean, Safe Email

High quality email anti-spam and anti-virus filtering is at the heart of what we do and forms an integral part of our Gateway, Mailcore and Zimbra solutions.

Anti-Virus Filtering

After a long period of evaluation, we chose AVG and Clam AV as the best anti-virus solutions for email scanning. Each message is tested for virus signatures from a database that is updated every 15 minutes, 24/7. We even check inside compressed files. Any detected virus is removed if possible and sent with an alert notification to the end user. Several options are available to control how notifications work.

Anti-Spam Filtering

Our array of anti-spam filtering servers run SpamAssassin, an open source email content analyser. Each email is subjected to a series of tests mainly focussing on it’s passage through the Internet, as well as text content. Each test gives a score. The scores are totalled and if the total is above a set threshold, the message is deemed ‘spam’ and subjected to your choice of handling rules. The message can be quarantined or forwarded with a modified subject or message header.

The Truth About Spam Detection

When evaluating an email filtering solution, be wary of ‘guarantees’ that you’ll no longer receive spam. There is no hard and fast way of detecting a message as being spam, only levels of probability. One person’s spam is another’s fantastic offer. We concentrate on emails that have taken measures to hide their origin rather than actual content. We can’t promise that you’ll never receive another annoying email, but it will be a very rare occurrence.
