[otrs] if subject has [spam], send to "SPAM" queue and *NO* autoresponse?

hi, i have this rule: $Self->{'PostMaster::PreFilterModule'}->{'1-x_Spam'} = { Module => 'Kernel::System::PostMaster::Filter::Match', Match => { Subject => '^\[spam\].*$', }, Set => { 'X-OTRS-Queue' => 'x_SPAM', }, }; how do I also tell it not to autorespond if this rule matches? -- ; Jay Vaughan
