Why does postfix (2.6.1, 2.7.0) force NOTIFY=NEVER when i change a RCPT TO: from a milter?

[Fredrik Söderblom]

Hi,

Why does postfix (2.6.1, 2.7.0) force NOTIFY=NEVER when i change a RCPT TO: 
from a milter?

E.g. doing a delrcpt("old rcpt") and addrcpt("new rcpt"), forces NOTIFY=NEVER. 
Log snippet:

Sep 23 22:02:26 seafox postfix/smtp[29516]: > 
smtp.domain.cc[192.168.254.253]:25: RCPT TO:<new-u...@domain.cc> 
ORCPT=rfc822;new-u...@domain.cc NOTIFY=NEVER

I've searched the source for 2.6, but fails to spot why the originator wouldn't 
want to be notified on failures when
only the recipient have changed.

It seems like the following snippet from smtp_loop() (smtp/smtp_proto.c) adds 
it, however i can't find where
rcpt->dsn_notify get's set to 1 when doing a smfi_delrcpt/smfi_addrcpt() combo.

                if (rcpt->dsn_notify)
                    vstring_sprintf_append(next_command, " NOTIFY=%s",
                                           dsn_notify_str(rcpt->dsn_notify));

Attached perl snippet will demonstrate my problem, tested on 2.6.1 and 2.7.0.

I would greatly appreciate any pointer in what i am doing wrong or missing.

/f

#!/usr/bin/perl

use Sendmail::Milter;
use strict;

sub eom_callback
{
        my $ctx = shift;

        $ctx->addrcpt("<new-us...@domain.cc>") or print("failed to add 
address.\n");
        $ctx->chgheader("To", 1, "new-us...@domain.cc") or print ("failed to 
change header.\n");
        $ctx->delrcpt("<old-us...@domain.cc>") or print("failed to delete 
address.\n");

        return SMFIS_CONTINUE;
}

my %my_callbacks =
(
        'eom' =>        \&eom_callback,
);

BEGIN:
{
        if (not Sendmail::Milter::setconn("inet:123...@localhost")) {
                print("Failed to detect connection information.\n");
        }

        if (not Sendmail::Milter::register($ARGV[0], \%my_callbacks, 
SMFI_CURR_ACTS)) {
                print("Failed to register callbacks for $ARGV[0].\n")
        }

        if (Sendmail::Milter::main()) {
                print("Successful exit from the Sendmail::Milter engine.");
        } else {
                print("Unsuccessful exit from the Sendmail::Milter engine.");
        }
}
