Spam Filtering (Domain Level)
How to get hereUse the Domain Level Antispam settings to enable, change, and disable various antispam filters for the selected domain.
- Premium Filter. (optional in the IMail Premium suite only). Provides fully automated spam protection in addition to the Standard antispam filter included in IMail and IMail Plus.
- Statistical Filter. Examines each word in the body of an email message to determine if the email is spam.
- Phrase Filter. Searches for spam phrases within the body of email 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 email.
- Enable content filtering for authenticated users. Select this option to enable content filtering for all messages that are received from authenticated users.
Note: Even if the Enable content filtering for authenticated users option is selected, content filtering is not performed on messages that are sent from system and host administrators. This prevents mail from being filtered twice in cases where a message is misidentified as spam and the administrator then forwards it on to its intended recipient.
- SPF (Sender Policy Framework). Enables stronger authentication of email senders using Sender Policy Framework (an extension to the DNS system). Provides administrators increased capability to stop incoming email from forged (spoofed) email addresses.
- Connection Checks. Verifies that the party connecting to your server is not part of a black list.
