12.12.5 Spam Filter Keywords

Keywords: destinationspamfilterXoptin, sourcespamfilterXoptin, disabledestinationspamfilterX, disablesourcespamfilterX

destinationspamfilterXoptin specifies that all messages destined to this channel are run through filtering software X even if those services are not specified by user or domain with the LDAP_OPTINX LDAP attributes. (Filtering software X is defined by spamfilterX_library in option.dat.) The optin parameters follow the keyword and the available parameters depend on the filtering program. For example, Brightmail parameters are normally spam or virus or spam,virus. The SpamAssassin parameter is spam.

sourcespamfilterXoptin specifies that all messages originating from this channel are run through filtering software X. (Filtering software X is defined by spamfilterX_library in option.dat.) The system-wide default parameters follow the keyword and the available parameters depend on the filtering program. If switchchannel is in effect, this keyword is placed on the switched-to channel.

sourcespamfilterX and destinationspamfilterX do the same thing as destinationspamfilterXoptin and destinationspamfilterXoptin, but don't accept optin parameters. They are used with filtering software that do not pass parameters and are simply enabled or not.

disabledestinationspamfilter X disables spam filter X for messages destined to this channel. If a message came from a channel that enabled spam filter X (example: destinationspamfilterXoptin) or the filter was enabled through the use of optin attributes in a user or domain LDAP entry, this keyword will disable it.

disablesourcespamfilterX disables spam filter X for messages coming from this channel. If a message is sent to a channel that enables spam filter X (example: destinationspamfilterXoptin) or the filter was enabled through the use of optin attributes in a user or domain LDAP entry, this keyword will disable it.
