Dolphian's anti-spam solution offers unparalleled performance and flexibility, with drastic operating costs reductions for Internet Service Providers of all sizes.


Junk mail is a challenge to customer satisfaction and customer relationship

When 70% to 80% of e-mail flows are spam, ISPs have an obligation to clean their subscribers' mailboxes in order to maintain customer satisfaction, and retain the mailbox as a privileged customer relationship vector.

Server overload induce uncontrolled costs.

Additionally, although e-mail is offered as a free service, it does not come free for the Internet Service Provider, and spam generates unnecessary costs on server capacity, storage and management.


Filtering e-mail has been a challenge for ISPs for several reasons:

  • Operational risk: additional overhead and resource consumption derived from low quality anti-spam software may jeopardize mail server operation
  • Business complexity: it is not acceptable to lose customer emails, or refuse legitimate emails, but not really better to deliver junk mail... now who is going to fine tune the filters?
  • Technical complexity: spammers are motivated, they change technologies on a regular basis in order to go through the filters, and it is not the best use of an ISP's resource to dedicate time and energy to fighting spam
  • Keep it STABLE: nobody likes adding new elements to a production infrastructure, let alone potential points of failure Dolphian USP

Deployment is a breeze as there are several possible deployment strategies.

Dolphian MCS can be deployed directly on the servers running the MTAs, on existing or new SMTP gateways, or even on the delivery servers. There is no known limitation to the number of parallel load-balanced Dolphian MCS servers an ISP can deploy, although at over 100 messages per second on entry level servers, our clients are often in for a good surprise.

Fail-over management is part of the Dolphian MCS protocol, for total risk control.

Of course, Dolphian's professional services department, and Dolphian's partners are here to assist on planning, prototyping, deploying and managing as needed.
