I will not post instructions to throw away non-delivery notices. I know that people would mis-use this to cover up their mistakes so that their users don't find out that mail was mis-handled.If you have a specialized need that never needs to deliver NDRs, then it is easy enough to edit the Postfix SMTP client source code and change the SMTP_STATE_DOT reply handler so that it skips the server reply code test.

You're probably right, I will not edit the source code, too much work to spraid the change over all the servers and to keep them updated. I will just keep using the NULL, thanks for your help anyway.
