Hopefully somenone can help in this matter. I've just started with VPS webserver administration and I don't have much experience with mail programs.

I received the following mail on my postmaster account:

Return-Path: <>
Received: (qmail 11279 invoked for bounce); 1 May 2010 05:00:03 +0200

Hi. This is the qmail-send program at xx-xx-xx.webhostprovider.com.
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.

<list@hostname.myhost.com>:
Sorry, I couldn't find any host named hostname.myhost.com. (#5.1.2)

--- Below this line is a copy of the message.

Site list is missing: mailman

It seems to me like somebody tried to get account passwords. I did not work on server for sometime.
I changed domain names in this message, prefixes are as in original message.
"hostname.myhost.com" is internal server name, not available in DNS.

Somebody have any idea what happened? Perhaps this is automatic message from mailman? I don't use mailman, it has been automatically installed

According to the email, the email send automatically by the server. Please make sure that you have not set any cron to send email.

Yeah id check your crontab and check this file.
/usr/lib/mailman/cron/mailpasswds

And Tbh if you dont use it, Rename the files to something like.

user@blaa# mv /usr/lib/mailman/cron/mailpasswds /usr/lib/mailman/cron/mailpasswds.OLD

I think the mail came because the account of the person has removed from the server to whom you wanted to send the mail.

Thanks guys.
I was not sure what was going on because I did not setup any cron jobs. Cron job is probably automatically configured during server setup. I renamed mailpasswds and need to check other cron jobs because actually I don't see crontab entry for such job (in mailman cron directory).

because I did not setup any cron jobs.

Probably not. BUT have you been trying to setup mailman? (It's a mailing list tool that comes bundled with most cPanel installs)

NO, I did not tried to setup mailman. I am using Parallels cpanel, and I found out that mailman was initially installed.

Parallels cpanel

So it's Plesk then NOT cPanel?
