Sentry Outbound

Spam is usually thought of as a problem affecting inbound email traffic. However, many ISPs find that their outbound email systems or IP addresses are being blocked or blacklisted because some of their users are abusing their servers for spamming operations. This taints the reputation of the service provider and also causes great inconvenience to legitimate users whose emails may also be blocked. It is in these situations that spam becomes much more than just a nuisance. TTAsia has developed a robust solution that helps service providers filter out spam from outgoing email flows, while ensuring reliable service for legitimate users. The Spam Mitigation Delivery Service (SMDS) takes a two pronged approach to mitigating the problems associated with outbound spam- TTAsia's proprietary outbound mail management system and its Postmaster Service.

Outbound mail management

Outbound mail passing through TTAsia's proprietary outbound mail system can travel towards its destination via two routes- Verified and Unverified. Email that successfully clears TTAsia's comprehensive Anti-Virus and Anti-Spam (AV/AS) system passes through the Verified server. The Verified server has a strong and trusted reputation, ensuring that emails passing through it are highly likely to reach their destination without being blocked. Outbound emails that are deemed suspicious by the AV/AS system, will still be sent out, but through the Unverified server.

Postmaster Service

TTAsia analyses and stores huge volumes of spam-related intelligence from its large user base (over 76 million) and is in constant dialogue with major anti-spam centers and email service providers. TTAsia leverages its expertise, trusted reputation and strong relationships with the internet community to offer its customers a valuable Postmaster Service, including:

• Resolution of problems related to black-listing and blocking by third parties
• Advice and information about anti-spam policy making
• Assistance with outbound spam-prevention techniques
