Hi, Thanks for your reply. The content_filter I use on my test platform is the simple example from http://www.postfix.org/FILTER_README.html#simple_filter I tried to override the *_bcc_maps on the main smtp daemon because with this filter, mails are resubmitting via the 'sendmail' command so I don't have this second smtp transport to perform my test on. Though I may try the override setting on the pickup entry of the master.cf file (?) Even if this test setup seems "awkward", shouldn't the first bcc be ignored anyway ? BTW I have already tried a similar setup with amavis (with 2 different smtp transports) and had the same problem. I will update my test platform and make a new test with amavisd-new and "smtp-resubmission" (thus a different transport) and will post my results accordingly. Thanks for your time. Emmanuel
