Spam Filtering (Domain Level)

Use the Domain Level Anti-spam settings to enable, change, and disable various anti-spam filters for the selected domain.

Premium Filter. (Optional only with IMail Premium). Provides fully automated spam protection in addition to the Standard Anti-spam 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 Blacklist. 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.
SPF (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.
Connection Checks. Verifies that the party connecting to your server is not part of a blacklist.
Logging. Controls where the standard anti-spam logs are written as well as how much detail is provided in them.
