Hi. This is the qmail-send program at plesk_server.com.
I tried to deliver a bounce message to this address, but the bounce bounced!

<anonymous@plesk_server.com>:
This address no longer accepts mail.

--- Below this line is the original bounce.

This is a permanent error; I've given up. Sorry it didn't work out.

194.116.198.32 failed after I sent the message.
