But I haven't any change. I am running postfix as it was. I observed the
thing when I fixed the problem with the ID and posted a test message.

I wrote VERP because, I remember such a setting exists. But in fact I
haven't changed anything.

Is this happening because few message to that ID had bounced and mailman
wants to be careful while sending mail to that ID so that in case it
bounces it will be easy to find the recipient address and increase his
bounce score ??
