How does The Outgoing Filter Work?

Diadem’s outbound spam and virus filter is a gateway solution. Activation is extremely easy and goes via the web interface or by using the API directly. The implementation can be done through a smart host setup where all outbound emails from your network are re-routed through the filtering systems, before going out to the internet. The alternative is to authenticate on a per user basis where the filtering systems are directly used as outgoing SMTP servers. Securing your IP reputation can be achieved with a few simple clicks!

FAQ Most frequent questions and answers

  • Why outbound filtering?

    The outbound email filtering prevents spam from being unknowingly sent out of your network through

    a compromised account or script. You can protect your entire network by monitoring all outgoing email traffic, identifying and locking down compromised user accounts. Outgoing filtering helps you to keep your network free of outbound spam and IP addresses away from blacklists.

  • Is there a control panel I can access to check outbound email?

    Yes. You will be able to access the outgoing anti spam control panel via the login link which will be provided by our support team.

  • How will the outgoing spam filter work?

    Configuration is done through a smart host setup where all outbound emails from your network are re-routed through the filtering systems, before going out to the internet. The alternative is to authenticate on a per user basis where the filtering systems are directly used as outgoing SMTP servers.

    Once configured outgoing e-mails are no longer sent directly to the receiving mail server, but are re-routed via the cloud antispam cluster. If the e-mail is valid, it’s forwarded to the final recipient. If it’s spam, it is blocked at the cluster.

  • How easy is it to deploy the outgoing antispam filter?

    The actual filtering of the messages is done on the highly redundant Antispam Hosted Cloud. This SaaS solution is fully managed, maintained, and 24/7/365 monitored by an expert team of experts.

  • Do I have to pay for each individual email address that I want to protect?

    No, our outgoing antispam spam protection is per-domain.
