Me too: I can observe this message in the logs for every message checked, yet I have network tests enabled.
Maybe this is normal, given that, in Debian, the DCC plugin is by default not loaded. Here is where DCC_CHECK is defined: ===File /usr/share/spamassassin/25_dcc.cf=================== ifplugin Mail::SpamAssassin::Plugin::DCC full DCC_CHECK eval:check_dcc() describe DCC_CHECK Listed in DCC (http://rhyolite.com/anti-spam/dcc/) tflags DCC_CHECK net #reuse DCC_CHECK endif ============================================================ notice that, on a standard distribution, it is undefined, because the DCC plugin is not loaded. This means that the definition of DIGEST_MULTIPLE should be different depending on whether the DCC plugin is loaded or not. An alternative approach that works for me could be to add this where DCC_CHECK or DIGEST_MULTIPLE are defined or scored: if ! plugin(Mail::SpamAssassin::Plugin::DCC) header DCC_CHECK exists:name-of-a-nonexistent-header-lfhfjkds score DCC_CHECK 0.01 endif -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
