Hi,
i recently received an e-mail from abuse@rackshack.net
informing me of this:
"We received notice that a site on your server (207.44.200.14) is causing a
portion of your netblock to be black-listed in various databases:
(http://spews.org/html/S1914.html)"
The ip address of 207.44.200.14 is indeed one of mine. I looked
at the report located at the provided URL and listed next to
that ip address is the domain 1-yes.com
This is a domain that I've never heard of, so I did an nslookup
on it and sure enough it resolves to my ip address 207.44.200.14
Also, the MX record for that domain is also set to my ip address.
This isn't by my doing, however.
I spoke to someone in support today and was told that the
spam e-mails are originating from my server and that I must
be running an open relay. I don't run any mail server
software on any of my rackshack boxes, so I can't be running
an open relay. A port scan of the box reveals that only the
SSH port and HTTP (80) are open. Also, my HTTP server
is configured to serve only static HTML files, so there aren't
any mail related CGI scripts that can be exploited.
Does anyone have any suggestions on what might be going on?
I'm not familiar with SPEWS - does that report indicate that
e-mail or e-mails originated from my actual ip address?
Any help or suggestions would be greatly appreciated.
- Ronin
ps. the server is always kept up-to-date with latest patches
and latest kernel.
