note: OUTGOING SPAM usage is not recommended because all ASSP DNS antispam checks cannot be applied locally and only a very limited number of ASSP filters can works locally ; you should enable this feature only if strictly required and only if you are an experienced ASSP administrator and you know what are you doing. If you enable OUTGOING SPAM Local users could be blocked incorrectly when they send email and you should take actions in ASSP GUI to allow them. For example if you find a good local user blocked incorrectly in ASSP log by Bayesian filter you should allow him using noBayesian_local in your ASSP WEB INTERFACE GUI.
