SPAM Blocking

Overview Hexamail's server antispam filter eliminates the cost, time and frustration your workers spend on unsolicited email (junk/spam) by blocking the majority of spam email before they ever reach your mailserver. Hexamail's multilayered antispam filtering ensures the best of breed techniques are used to provide total protection from all email bourne threats including spam, malware, spoofing, phishing and virus. Automatic built in heuristics are combined with admin and user configurable rules and optional features such as greylisting and challenge response to allow you to tailor your spam solution to your exact needs. Unlike the majority of other antispam solutions, Hexamail is a server software solution that runs on your network so your email is never sent to the cloud or any third party servers for analysis. This ensures your privacy is guaranteed, eliminates any additional latency in receiving email and prevents your email being dependent on a third party service that can suffer downtime or hacking. Integrated analysis of outgoing email traffic ensures false positives are minimized by automatic whitelisting.

In some instances it is desirable to prevent emails to or from certain sources or destination companies. For example, perhaps you wish to ensure that no emails from recruitment agencies or ex-employees reach your staff, or prevent all outgoing emails to a competitor. In other situations it is the contents of the email that requires blocking. This can often be outgoing or incoming offensive material, such as pornography, swearing, or other undesirable material. Blocking works in concert with alerting to ensure that emails can be systematically blocked, stored and a nominated party alerted to the incidence of the blocked email.

Overview Incoming emails can place a huge burden on the nominated recipient. Often several email addresses are provided publicly for information, questions and other telemarketing activities. More often than not emails arrive to all addresses about a diversity of subjects, with little relationship between the email address and the subject matter. For example, a company-wide email address such as will receive speculative employment queries, requests for information, invitations to tender, unsolicited junk mail, technical support questions etc. etc.

Having a single nominated recipient quickly results in the recipient becoming over-burdened with email. Studies show that having multiple recipients results in no one giving the incoming message stream the required attention.

The solution? Intelligently route each incoming mail based on the nature of the subject, content, and any attachment to the most suitable respondent recipient.

Routing uses rules concerning the subject line, contents, and previous message chain to ensure that the correct recipient is initially identified and then continues the correspondence when required.

Hexamail Secure module provides a centralized automatic email security solution. It enables signing, verification, encryption, decryption using PKI X509 certificates and also Domain Keys Identified Mail (DKIM) functions on outbound email. PKI certificates are easily managed and multiple security policy rules can be setup to dictate which email is signed, encrypted, decrypted and verified. Email security failures can be quarantined for administrator inspection. DKIM is used to sign email from your domain so that the recipient knows that they have not been spoofed. Hexamail helps you manage your DKIM signing public/private key pairs and the required DNS entries for DKIM.

Anti Spoofing

Removes the ability of malicious parties to spoof email from your domain using Domain Keys Identified Mail (DKIM)

Automatic Key Creation

Hexamail automatically creates the required crytopgraphic public/private key pairs required for DKIM signing. The private key is held securely on your server

DKIM Selector Management

DKIM allows for multiple different selectors (or key pairs) to be used for signing. Hexamail manages these and automatically signs email with the appropriate selector

DNS Entry Generation

The Secure module automatically generates the DNS entries required for the DKIM signature verification process, allowing recipient servers to verify your email signatures. Simply cut and paste the generated DKIM DNS entries into your DNS management interface as a TXT record

High speed archiving

Native high-performance C++ archiving code ensures that emails are archived and indexed in realtime. The unsurpassed performance allows the archive to be used live by end-users to retrieve old, deleted, or difficult to find emails from a web-interface.

Massively Scalable

Archiving of 100s of millions of emails in a single archiver is possible, allowing many years of emails to be archived on a single server or drive.

Low Storage Requirements

All email content (MIME) is retained compressed, allowing accurate records to be retained while minimizing storage. Emails are automatically deduplicated. Save costs of storages devices, upgrading servers and backup time and facilities.

Fulltext search

Full-text indexing automatically takes place on archiving. This allows your valuable resource of archived emails to be leveraged for knowledge management, auditing and discovery within your organization.

Genuine Archiving

Some inferior archiving solutions simply push email content into a relational database. This can be costly in database licenses, slow to retrieve email and extremely demanding of disk space and other machine resources. Be sure to check the licensing implications and costs of such systems before purchase. Hexamail is a complete solution requiring no third party database licenses.


Archiving takes place on your servers, within your network. Sensitive emails need never leave your organization, eliminating trust, hacking, or security breach concerns typical of third party service based archive solutions providers.

Regulatory Adherence

Full MIME storage ensures your chosen email archive solution adheres to all regulations now and in future. Regulations such as Sarbanes-Oxley can be costly to implement, Hexamail Vault eliminates the cost for archiving email in a compliant way.


A unique index design allows email content to be backed up and removed from the live server to secure/offsite backup facilities. The fulltext index remembers which emails were in which backup files and allows fulltext search even over email removed from the server.
