Hi,
I do some checks in a mail server and i found this strange problem.
Sometimes I've received "failure notice" email who contains the
original message "--- Below this line is a copy of the message." but
with strange email in the error text...
Delivered-To:postmas...@mydomain.it
Date: xxxxxx
From:mailer-dae...@mydomain.it
To:postmas...@mydomain.it
Subject: failure notice
Hi. This is the qmail-send program at mailbox.ptavant.it.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<strangeemail1@somedomain>:
User and password not set, continuing without authentication.
x.y.z.k does not like recipient.
Remote host said: 550 Requested action not taken: mailbox unavailable
Giving up on x.y.z.k .
<strangeemail2@somedomain>:
User and password not set, continuing without authentication.
x.y.z.k does not like recipient.
Remote host said: 550 5.1.1 <strangeemail@somedomain>: Recipient address
rejected: User unknown
Giving up on x.y.z.k .

Return-Path: <postmas...@mydomain.it>

...But strangeemail1 somedomain and strangeemail2 @ @ somedomain were
not the recipients of the original email.
In additional.... some days ago mail server was attacked with a relay
attack. IT operator resolved the problem by changing an compromised
password and rebooting server a few times (qmail supervise was locked).
In queue/bounce i found 4000 files oldest than one week and Local and
remote queue have only 6 email. I think the problem mentioned above is
related to the files found in the queue / bounce but could not find
anything about it.
Suggestions? Can i delete (or move) bounce files or is there a
qmailtoaster command to do it?
thank you
