The content filter sends messages back info Postfix similar to http://www.postfix.org/FILTER_README.html#simple_filter It is worthwhile to know if the duplicates are caused by adding multiple 'always_bcc' addresses to the same queue file. Look for logging with "message-id=". Mar 4 01:05:05 mail postfix/cleanup[30124]: foo: message-id=<b...@some.mta.name For each message-id value, there will be logging from before the content filter, and logging from after the filter. Look for "qmgr" logging with "foo", and note the "nrcpt=<number<>" which indicates the number of recipients. Compare the numbers before the content filter and after the content filter. Mar 4 01:05:05 mail postfix/qmgr[28026]: foo: from=<sen...@example.com>, size=1234, nrcpt=1 (queue active) It will give an idea why you get three copies. Wietse
