Email Spam Protection

Overview

MailRoute's spam-filtering service passes all email through a multi-layered spam filtering system that identifies up to 96% of inbound spam. This processing takes place outside your network, reducing your traffic and email server processing loads. Since email is blocked at the Internet gateway, users no longer have to sort through and delete spam email in their inboxes. MailRoute acheives an extremely low false-positive rate - 1 in 250,000 messages.

How It Works

Since MailRoute is a fully managed service, implementation of the Anti-Spam service requires only that you sign up with MailRoute and then make a simple change to the DNS records for your domain. There is no interruption in your email services during the implementation period. There is no software or hardware required.

Once the DNS change is made, email will start flowing through the MailRoute network where each message is inspected by our multi-layered spam filters. Clean email is delivered to your email server, and spam is tagged or quarantined, depending on your preferences. Spam is no longer stored on your corporate network.

FAQs

Q. How effective is MailRoute's spam filtering service?

On average, we recognize and filter over 90% of incoming spam. Some users report recognition rates of 96% or higher.

Q. What happens to email identified as spam?

We allow you to set the parameters for spam detection. You can have any or all spam redirected to a web-based repository. Or you can have it delivered with a modified subject line or an additional email header. You can even choose to filter out highly spammy email, while tagging and delivering email that has few spam characteristics.

Q. Is my email confidential?

Internet email is inherently insecure - it travels over public networks and through multiple servers on its way from source to destination. MailRoute processes each email, looking for spam and viruses, and then delivers it to the destination. We don't view or store it for any other reason.

Q. Does MailRoute use a whitelist, and how can I ensure that friendly email addresses are not blocked?

Yes, MailRoute uses a whitelist. You may whitelist any addresses you choose on a per-user or domain-wide basis.
