Cloud-Based Spam Filtering

Remarkable accuracy
Unlike other spam filtering systems that rely on algorithms that spammers can easily defeat, our rule based system features million of rules that are constantly updated and maintained

Zero-Hour Virus Protection
Like other spam filtering solutions, we use popular virus scanners to help block viruses. These scanners do catch some viruses, but we have added our own detection systems that watch for patterns and automatically block new viruses hours before commercial virus scanners have been updated.

Almost ZERO false positives
A “false positive” is when a good email is blocked by a spam filter. While other spam filters use automated systems to “auto-learn” spam, a process that is prone to errors, our rules are carefully engineered to ensure that only real spam is blocked.

Quarantine viewer for all users
Rather than just deleting spam that is blocked, all spam is placed in an easy-to-use domain-wide quarantine where it can be viewed by you, further ensuring that no good email is ever lost. Optionally, you can set up a separate quarantine for each user on your domain.*

Access to message logs
We provide 30 days of delivery logs for each clean message so that if a message goes missing, you can easily track it down.

Automatic mail spooling
If your mail server goes down, our service will automatically hold your clean messages until your mail server is back online. Mail is automatically held for up to 30 days.
