We have a cluster. Tell 2 boxes :
All web requests are load balanced to the node1.
The cluster manager runs others services as smtp/pop/imap/…
One of our client send emails from a PHP scripts. As the web requests are done on the Node1 the mail is send from node1.mydomain.com
The problem is that we receive (the postmaster of this node) Huge numbers of failure notice emails and our client doesn’t.
for example email like this one

I do not understand why our postmaster (/var/qmail/alias/.qmail-postmaster) receives this mail ?
Why this mail is not sent to our client ?
This issue happens only for THIS client domain !
