Hexamail's anti-SPAM module eliminates the cost, time and frustration your workers spend on unsolicited E-mail (junk/SPAM) by blocking the majority of SPAM emails before they ever reach the user.
Using automatic built in heuristics combined with all the best known techniques such as pattern matching, connection restrictions, ORB, real-time black hole lists and any desired additional administrator controlled rules it offers the most comprehensive toolbox for effective SPAM blocking available.
The combination of best of breed SPAM blocking techniques ensure almost all SPAM is stopped in its tracks, while the automatic analysis of outgoing email traffic ensures false positives are minimal. The SPAM filtering software is entirely under your control, with no privacy, security risks and no additional latency introduced into your email system as is the case with many hosted solutions.
Automatic white list generation from senders contacts and email message threads coupled with intelligent on-the-fly white list detection. This ensures legitimate senders email do not get blocked by the SPAM blocker
Challenge-response features to allow senders to verify and have email automatically accepted and their address whitelisted
Temporarily fail connections from new IP, sender and recipient sets to effectively block spam software, and BotNets. Automatically whitelists your regular senders so that no delay is experienced for legitimate communications.
Dynamic Adaptive Honeypot. The Honeypot uses spam sent to chosen honeypot addresses to automatically generate adaptive intelligent agents, known as "bees". These identify and block similar spam. This provides realtime protection against new spam types, sender IPs, and specifically image spam.
Full Bayesian statistical pattern matching providing highly accurate (better than 99%) spam blocking with minimal false-positives (emails incorrectly marked as spam). Selectable pattern matching subcategories allowing bypass of pattern matching for specific types of spam, such as 'Money Making', 'Recruitment', 'Privacy', 'Competitions' etc. Multiple thresholds for pattern matching allowing marking, blocking or automatic deletion of identified spam. Email accepted or deleted from the quarantine is used to further the Bayesian matchign for future email.
Easy to use white list management facility allowing you to maintain lists of email addresses that you never want blocked. Users each have their own personal white lists and senders can be automatically whitelisted if a blocked email is released from the quarantine.

Instead of having to laboriously enforce corporate signatures in every email client in your organization, Hexamail Guard allows you to configure a corporate signature once and have it automatically added to all outgoing email. This helps prevent additional network traffic from redundant signatures on internal emails and ensures you can be confident that every external email will contain the required signature.

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.

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 mail@yourcompany.com 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 Archiver module provides is a centralized automatic email archiving solution.
Highly efficient full-text indexing and compression algorithms ensure that the most scalable
and high performance email archive is generated entirely automatically from all of your email.
Hexamail's email archive software leverages state of the art indexing and compression technology to create the most compact
and high performance index of email data. Inferior solutions often simply push emails to relational databases or worse, file systems.
Such systems suffer from poor scalability, lengthy query/discovery times and extremely high storage requirements: often requiring
more space for the archive than the original emails!
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.
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.
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.
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.
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.
Active Directory integration allows automatic import of your users and restriction of their access to only their emails
Full secure SSL access to web based knowledge management, discovery and search interfaces.
The Archiver module can index email from almost any source including Exchange, maildir, mbox, hMail, iMail, MDaemon, Hexamail, POP3, SMTP, and PST
Index email driectly from Exchange 2000 onwards
Index any PST files from Outlook clients or Exchange server
Content can be retained for periods matching typical regulatory requirements such as Sarbanes Oxley, European Union ISP Communications Data retention, SEC Rules, NASD, HIPAA and Graham-Leach-Bliley Act.
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.
Automated export features allow all email matching specific complex criteria to be exported to directories or zip files for litigation or auditing purposes.
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.
Live-access allows your end-users to access the archive through a web-interface and retrieve email they may have deleted or lost in their inbox. This simultaneously ensure valuable knowledge is never lost from your organization, can be quickly retrieved, and users reduces user inbox storage requirements.
Redelivery or historical email to selected recipients allows verbatim copies of emails to be retrieved and redelivered in a single click.
Users can run their own audit and generate folders or zip files of vital emails for meetings, storage offsite or presentation to management.
Administrators can restrict access to discovery features to specific users or areas of discovery
