Spam Filtering (Domain Level)

How to get here

Use the Domain Level Antispam settings to enable, change, and disable various antispam filters for the selected domain.

• Premium Filter. (optional only with IMail Premium). Provides fully automated spam protection in addition to the Standard Antispam filter included with all IMail products.
• Statistical Filter. Examines each word in the body of an e-mail message to determine if the e-mail is spam.
• Phrase Filter. Searches for spam phrases within the body of e-mail messages and identifies the messages that are spam.
• HTML Features Filter. Searches HTML features in messages that are subject to spam. Sets how many HTML features must be present in an .htm file in order for a message to be identified as spam and the spam action to take.
• URL Domain Black List. Searches for domain names that appear as URL links in messages, and lets you set the action to take on such messages.
• Broken MIME Headers. Uses the Broken MIME Header Filter to identify MIME Header characteristics that result in SPAM e-mail.

  Note: Content filtering for authenticated users can be enabled or disabled for all the antispam filters listed above on the domain properties page of an IP'ed domain.

• SPF How to get here (Sender Policy Framework). Enables stronger authentication of e-mail senders using Sender Policy Framework (an extension to the DNS system). Provides administrators increased capability to stop incoming e-mail from forged (spoofed) e-mail addresses.
  • From the home page, click the AntiSpam > SPF tab. The SPF page appears.

   

• Connection Checks. Verifies that the party connecting to your server is not part of a black list.
• Logging. Controls where the standard antispam logs are written as well as how much detail is provided in them.
