PreciseMail Anti-SPAM Gateway


PreciseMail Anti-SPAM Gateway (hereafter 'PreciseMail') is an advanced product to fight spam. PreciseMail works there, where it can be most effective: where a message enters your organization. This provides important advantages compared to other solutions: it is easier and more cost-effective to fight spam in one place, instead of having all your employees take their own measures. As PreciseMail operates on the interface between the Internet and your internal mail environment, you can also prevent sending back auto-replies (among which 'out-of-office' notifications). Finally, abuse of your costly resources is being minimized. A simple computation shows you the costs that comes with spam and what you can save by deploying the proper anti-spam software.

How does PreciseMail eliminate spam?

  • PreciseMail combines a so called 'Bayesian artificial intelligence engine' with an advanced analysis of messages ('heuristic analysis'). The result is a very accurate anti-SPAM filter. 'Bayesian filtering' is based on statistical analysis of a message, including header information. On the website of Process Software more information can be found.
  • Filters can be adjusted to the needs of your organization. The filters in PreciseMail have scores, with reasonable defaults during installation. These scores can be modified if this suits your organization.
  • End users can maintain easily their own 'whitelists' and 'blacklists' via an intuitive web interface. This lowers the amount of system management required and furthermore provide the end users with the possibility to change their preferences or to opt-out of scanning (this can be controlled by the administrator)
  • Apart from user-level 'whitelists' and 'blacklists' it is possible for the administrator to define site-wide 'whitelists' and 'blacklists'.
  • When PreciseMail encounters a (potential) spam message, there are various options:
  • the message is discarded
  • the message is quarantined
  • the message is marked with header information reflecting the 'spamicity' of the message and the message is delivered to the mailbox of the recipient
  • the Subject of the message is modified to include a prefix or postfix (e.g. [SPAM]) and is delivered to the mailbox of the recipient
  • using one of the two latter options, it is possible to have the enduser apply their own 'rules' to filter these messages or to put them into a specific folder.
  • end users can get a regular (automatic) notification about their quarantined messages.
  • messages in quarantine, can be displayed and released by endusers without the need of operator intervention
  • at any time you can request a detailed report about PreciseMail activities.
