Anti-Spam Functionality
Added new anti-spam functionality to manage the influx of spam on your server. Anti-spam features include the following:
- Connection filtering checks various aspects of the connecting SMTP server to see if anything is indicative of a spammer.
- Specify e-mail addresses and domains that you trust not to send spam and do not need to be content filtered. (White List)
- Enter "trusted" IP addresses and subnets for which no spam filtering is done. (Trusted IP Addresses)
- Check to see if the sending IP address is that of a known spammer, by comparing it against configurable black lists. (DNS Black Lists)
- Connection validation tests, verify the "Mail FROM" address, HELO/EHLO domain information, and perform reverse DNS lookups for each message. (Validation Tests)
- Ability to immediately delete messages if they fail a certain number of black lists and validation tests.
- System administrators configure and enable black lists, and control which ones are available for the hosts.
- Host administrators control which black lists are available for the host, assuming the black lists are enabled for server.
- Pre-configured black lists, enable you to begin spam filtering immediately after installation.
- Ability to use the default DNS server configured for IMail Server to perform black list queries. This allows you to perform queries without relying on the black list's DNS.
- Content filtering analyzes the body of e-mail messages to determine if the actual message is spam.
- A configurable phrase list, for each host, searches for spam phrases within the body of a message. (Phrase Filtering)
- Analyze incoming e-mail, by comparing it against spam and non-spam word counts, to determine the statistical probability that the message is spam. (Statistical Filtering)
- Ability to have separate spam and non-spam word files for each host, or one file that applies to all hosts and is managed by the primary host.
- Advanced Statistical Filtering options allow experienced administrators to control the underlying functionality of the anti-spam engine.
- The Antispamseeder.exe command line utility allows you to manage the anti-spam word list (antispam-table.txt) and spam values contained in it. Using this utility you can customize the antispam-table.txt file for each host by adding, deleting and modifying words.
- An exclude list for each host excludes insignificant words from statistical analysis.
- Ability to enable/disable content filtering for authenticated users.
- Ability to enable/disable phrase filtering and statistical filtering separately.
- Configurable spam actions to take on messages that are identified as spam. You can select from the following: Delete, Forward to an address, or Insert an X-Header. Phrase filtering and statistical filtering spam actions can be different.
- Insertion of spam X-Headers when a message is identified as spam by any of the spam tests, including DNS black lists, validation tests, and content filtering. X-Headers also contain any information returned from the black list, explaining why an IP address is black listed.
- Ability to use IMail Server delivery rules to search for any of the spam X-Headers and to process the mail.
- Anti-Spam Logging tab, allows you to separate anti-spam logging from other IMail Server logging.
- An anti-spam message ID is inserted into every anti-spam log message, allowing you to track all events for a specific message.
Web Messaging Administration
- Added several new templates that allow for anti-spam administration from Web Messaging.
