Mail Filter Allows Individual Configuration for
Multiple/Virtual Users
Norwood, MA -- October 12, 2002 -- BSM Development (www.bsmdevelopment.com) announces the latest release of MailCorral, a mail filtration program, for use on Unix and Linux systems and available for download from the company's Web site. This release (version 1.0.11) allows ISPs and other sites with large numbers of users to provide individual filter and spam handling configuration for real or virtual users. Editing of individual user configurations is done through a Web UI which may be easily tailored to match the site's standard look and feel.
MailCorral provides virus and spam filtering at the system level for all mail delivered by sendmail. As a global system filter, global processing parameters are applied to all of the mail handled by MailCorral. However, users of the system on which filtering is taking place may prefer to set certain filtering and/or spam handling options according to their individual tastes. MailCorral now allows users, both real and virtual, to tailor how it filters their mail via individual config files or a configuration database.
Individual configuration file support allows a user to create a configuration file in their home directory where all of the local filtering options may be specified. These local options are applied to each message, based on the recipient of the message, with the recipient's username being used to look up and process their local options file.
For systems with virtual users, individual user support is still possible through MailCorral's DBM database configuration file. Using this option, all of the user settable parameters are stored in a single configuration database, which may be located anywhere. The virtual user's name is used to store and lookup configuration parameters and everything else works as if they were a real user.
A Web UI is provided through MailCorral's configuration editor which gives individual users a simple, easy to use method of editing configuration parameters. It is a CGI script that runs under your site's Web server. The user visits a configuration form, with their Web browser, where they see all of their configuration parameters and where they can edit them. Changes that are made to the form are reflected back to either their local config file or DBM database.
MailCorral is used to filter mail delivered to Unix and Linux systems via the standard Simple Mail Transfer Protocol interface. As such, it watches all mail traffic entering your system and inspects it for the presence of harmful viruses and annoying spam.
The advantage of filtering mail on the Unix/Linux system delivering it is that MailCorral can stop viruses and spam before they ever get to the recipients. This can reduce network traffic (for spam) and guarantee that a virus will not get launched by mistake.
In addition to MailCorral, SpamCorral is available, from BSM Development, for handling spam that has been sidelined and not delivered by the mail filter. Options allow the spam to be placed in a holding area, from whence a notification is sent to the recipients on a regular basis. If they decide, in response to notification, that they would like to see the spam after all, it may be automatically released from the holding area and delivered to the recipient.
A collection of test mail messages is offered which can be used to validate your installation's virus filtering and spam rejection capabilities (regardless of how they are provided). These test messages are specially-crafted to validate known methods of virus propagation, using killed viruses which can do no damage. Auditing your system's virus filtering capabilities, in this manner, is an excellent way to detect security holes and repair them before they are exploited by malicious users wanting to infect your system (think of it as vaccination for your system). Checking your system's spam rejection capabilities will prevent your users from being annoyed by and wasting their time with spurious junk.
Also available is an outbound mail redirector which can be used for small installations wanting to send mail from their internal networks through an Internet Service Provider that only accepts mail from individual users. Systems that must support multiple users and virtual domains through a typical ISP account will find this product useful.
