In this case the intention is not to block an IP, but to make a policy decision e.g. "if the IP is listed, amavis should not scan it for SPAM" or "if the IP is listed, it should use a policy bank with higher SPAM scores". The DNS(BL) mechanism is only used as a network based lookup table. Easy to distribute and it doesn't require a reload of all amavis instances 'reading' an IP list. p@rick > -- [*] sys4 AG https://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
