This is not a dupe. Please read and understand
the issue before marking this as a duplicate question that has been answered already.
Several customers are reporting bounce messages like
the one below. At first I thought their computers had a virus but then I received one that was server generated so
the problem is with
the server.
I've inspected
the logs and these email addresses do not appear in
the logs.
The only thing I see that I do not remember seeing in
the past are entries like this:
Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: hook_dir = '/var/qmail//handlers/before-queue'
Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: recipient[3] = '
[email protected]'
Apr 30 13:34:49 psa86 qmail-queue-handlers[20994]: handlers dir = '/var/qmail//handlers/before-queue/recipient/
[email protected]'
I've searched here and
the web and maybe I'm just not entering
the right search terms but I find nothing on this issue.
Does anyone know how a hacker would attach additional email addresses to a message at
the server and have them not appear in
the logs?

Dear

UPDATE: After not seeing this problem for a while, I personally sent a message and immediately got a bounce with several bad addresses that I know I did not send to. These are addresses that are not on my system or on
the server. This problem happens with both Mac and Windows clients and with messages generated from Postini and sent to users on my system.
This is NOT backscatter. If it was backscatter it would not have
the contents of my message in it.
UPDATE #2
Here is another bounce. This one was sent by me and
the bounce came back immediately.
