Custom Blacklist

The Black list is a custom database of email addresses & domains from which you never wish to receive emails. I.e. mails sent from these email addresses or domains will always be marked as spam.

The configuration of the blacklist is done from the Anti Spam > Custom Blacklist list node. Right-click on this node to bring up the Custom Blacklist properties.

Screenshot 32 - Adding a blacklisted email entry

To add a blacklisted domain or email address, click `Add'. Specify the full email address. If you wish to specify an entire domain, specify it as follows `*@spammer.com'. The `*' is a wildcard to include all email addresses from that domain.

You can also blacklist entire domain suffixes, for example *@*.jp. This will for example ensure that mail sent from Japan is automatically marked as spam. Clearly you have to use these entries with care.

Then specify whether you want the blacklist entry to apply to the MIME TO: field or the MIME FROM: field. The MIME TO option allows you to blacklist email sent to a non existing email address. This could be handy if you want to avoid an NDR being sent and just want the email to be automatically deleted (for example mail sent to ex employees).
