FIRST: Do NOT send debug logs if not requested because they are mostly useless verbose and contains not more informations as the obly interesting "mail for 127.0.0.1:10025 loops back to myself" We are using "check_recipient_access" and a table with a filter for each domain and i am püretty sure the "spamfilter" smtp instance does the trick master.cf: spamfilter unix - - n - 30 smtp -o disable_dns_lookups=yes -o smtp_data_done_timeout=1200 -o smtp_send_xforward_command=yes -o max_idle=1h -o max_use=1000 the domains having as example the value "FILTER spamfilter:[127.0.0.1]:10025" what means ypu can use different filters for different domains
