Hi. This is the qmail-send program at mxavas4.aruba.it.<br>
I'm afraid I wasn't able to deliver your message to the following addresses.<br>
This is a permanent error; I've given up. Sorry it didn't work out.<br>
<br>
<info@AAA.it>:<br>
message is looping &t.turilli@CCC.it<br>

I'm not going to try again; this message has been in the queue too long.<br>
