Spam Filtering That Just Works

Today, spam filtering is a must, not an option. By some estimates, as much as 90% of mail sent is spam. The filtering that’s included in the Tucows Email Service provides effective protection for users against spam and viruses.

Starting today resellers can provision what we call “filter only” accounts inside the Tucows Email Service. Cutting to the chase, the net result is that email is sent through our filtering system, spam is redirected to a quarantine, and only the legitimate mail is then directed on to our customer’s email server.

Last fall at ISPCON in San Jose, CA, I had the opportunity to give a presentation about our experiences running Tucows Email Service. I called it “Email Nightmares: Tales from the Edge” and in that talk I showed some of the pain points that email providers run into when managing messaging services. One of the most challenging aspects I called out was managing spam.

That’s all well and good, but some email providers aren’t ready, or don’t want to move to a fully-hosted email service right now. So we came up with an alternative that allows us to provide that same level of spam and virus protection, while allowing providers to continue to use their own email infrastructure.

The benefits are threefold:

  1. You’ll sleep better at night: you can focus on running your email servers, without having to worry about things like spam filters, or blacklists.
  2. Your servers will thank you: nine out of ten messages is spam, and we’re taking care of that before you have to. As a result, your server loads drop significantly.
  3. We’ve got your back: Tucows has a dedicated Abuse Team that is actively engaged in the battle against spam. We have experience managing abuse and we’ve forged strong relationships in the industry through organizations like the Messaging Anti-Abuse Working Group (MAAWG).

Our Tucows Email Service is built for ISPs and hosting companies. The goal with this filtering only option was to provide effective filtering for our customers that ‘just works’. Resellers have the option to provide a web-based spam quarantine where users can review email flagged as spam, and manage safe- and blocked sender lists.

Our Services website has more information including a screencast demonstrating the web-based spam quarantine.
