Our integrated Postfix policy server allows Mailspect to make pre-queue decisions on email handling. Mailspect can immediately disconnect hosts that are violating your policies thus saving you bandwidth and resources.

Mailspect includes the only integrated pre and post-queue filter for Postfix since we include both a Postfix Policy Server and a content filter. Both elements have an integrated configuration and communicate with each other to intelligently decide if a message should be processed before or after it is queued.

The following features are handled by the Policy Server.

Manual Blacklists
Email is rejected before if it is queued. Whether SMTP hosts are being blacklisted or email addresses MPP will immediately disconnect offending senders.

Automatic Blacklists
Mailspect has the unique ability to automatically black list hosts that violate your thresholds for message sending rates, spam rates, bad address attempts or content violations. MPP issues an immediate disconnect to hosts that violate your connection policies.

Address Verification with Auto Black List Abilities
Mailspect will query your address directory to verify the validity of addresses. Of course Postfix offers this but Mailspect goes beyond by offering per-domain configuration, flexible address storage and the ability to automatically block hosts that repeatedly send to unknown addresses.

Rate Limiting
Mailspect can issue defers to hosts that violate your policies thus rate limiting hosts.

Greylisting
Our policy server offers SQL based greylisting. Since Mailspect stores host entries in an SQL database multiple Mailspect front-ends can share the same greylist database.

Real Time Black Hole Lists
The policy server will perform RBL checks before a message is queued.

Whether you use Postfix as an email gateway, email server or it is embedded in your collaboration server, Mailspect will improve how you clean, process and save the email stream.   Mailspect Defense consists of a Control Panel, Mail Filter and Quarantine Solution that manages a multilayered suite of email defenses from one centralized interface.   Mailspect Archive includes a Tamper-Proof Repository, Discovery Engine and Message Viewer.

Mailspect understands the economics of running email gateways and offers flexible pricing models for email service providers, schools, governments and businesses.

Mailspect is updated via APT for Debian and Ubuntu and YUM for Red Hat.  It uses open source middleware such as Apache, Sphinx and MySQL as well as the Clamd and Spamassassin anti spam and antivirus engines. It also offers commercial AV/AS engines like Cloudmark, Mailshell and F-PROT in its Standard Edition.  Mailspect Defense supports ESET and Sophos through its Control Panel. This flexibility gives the systems adminstrator the freedom to customize and integrate without having to start over for every project. You will be surprised by the depth of Mailspect’s functionality; this functionality reflects years of meeting the requirements of the most demanding customers. Mailspect handles email archive, content-based processing, large scale anti spam, web services integration, content filtering and a lot more in one integrated product. Beyond email defense and archive, Mailspect offers a one-of-a-kind web services engine called Email Stream Management that integrates email with Salesforce.com, Google Docs, MySQL databases or any application with a web services API.

Mailspect is unique for Postfix in that it is the only software with an integrated policy server and content filter for pre and post-queue processing.
