Hi Thank you for your answer but I do not want to disable the DSN option.
I want to "temporarly" remove the esmtp "notify=SUCCESS" tag when I pass the message to the content_filter then I want to put it again within the "rcpt to" field. Doing that (if possible) the next hop relay could use the DSN information. The trouble I have here is that my content filter cuts the global DSN chain.
