Web-based Anti-Spam Management for Exchange

Exchange Anti-Spam Toolkit provides a web-based graphical user interface (GUI) to enable all aspects of anti-spam functionality in Exchange to be easily managed, even on Mailbox (previously known as Hub Transport) servers. It additionally provides support for URL or Domain-based Block Lists (also known as URI DNSBL or SURBL) and Sender Score filtering capabilities.

IP Block List Providers (DNSBL)

IP Block List Providers, such as Spamhaus, are one of the most effective spam filtering tools, and are easily configurable using the graphical user interface. See the documentation for guidance on how to configure the most popular IP Block List Providers.

URL/Domain Block List Providers (URIBL/SURBL/DBL)

URL or Domain-based Block List Providers, such as Spamhaus DBL, SURBL and URIBL are particularly effective for filtering HTML messages containing links, such as phishing messages and some malware. URL Block List Providers are an additional filter provided by the QSS Exchange Anti-Spam Toolkit.

Sender Score Filter

Each POP3 account can have separate delivery and routing settings. Automatic Recipient Detection supports catch-all mailboxes and is fully configurable.

Sender ID Validation & Sender Reputation

Sender ID Validation checks Sender Policy Framework (SPF) records of sender domains. Sender Reputation performs reverse DNS, open proxy detection and other checks.

Sender Filter

Specific senders and sender domains can be added to the block or allow lists (white lists).


The dashboard provides a quick and and easy way of verifying that anti-spam agents are correctly installed in your environment, and anti-spam filters are optimally configured.

Content Filter

The Content Filter provides basic analysis of the body content of messages, and supports custom lists of Allowed and Blocked Phrases.

Transport Agent Management

All third-party Transport Agents (not just QSS Exchange Anti-Spam Toolkit) can be managed using the web-based interface, without the need to use PowerShell commands. System Transport Agents can be viewed and the Priority can be adjusted.

Mailbox Junk Configuration

Junk mail settings for individual mailboxes can be viewed and modified, including mailbox-specific lists of allowed and blocked senders, valuable for troubleshooting purposes. Anti-Spam filters can also be disabled for specific mailboxes, and custom SCL thresholds can be set.

Anti-Spam Search

The Search feature allows administrators to determine why a specific message was or wasn't blocked. The exact rule or configuration setting affecting the specified email address, IP address or domain will be quickly located. Search includes mailbox-specific settings, allowing administrators to quickly determine if a specific user has erroneously configured anti-spam settings for their own maibox.
