How to identify our servers ?
Open the email you received from us in a seperate window (double click the email), and now go to File->Save and save it as an EML file somewhere in your system. Next, open Notepad (yes, Notepad) or any other plain text editor you would like and use it to open the saved EML file.
Now that the file is open you will see lines of text like this :
Return-Path: <[email protected]>
Delivered-To: [email protected]
X-Envelope-To: [email protected]
Received: (qmail 18381 invoked by uid 399); 13 Oct 2008 00:52:17 +0200
X-Virus-Scan: Scanned by ClamAV 0.91.2 (no viruses); Mon, 13 Oct 2008 00:52:17 +0200
Received: from mail.custonews.com (HELO mail.custonews.com) (104.243.35.138)
...
These lines are called headers.
Always look at the "Received:" headers to know exactly where did an email originate from.
As you can see in the example, we marked for you in bold the "Received:" header line that will most likely to appear on your email if it was originated from our servers.
What to do if you didn't find a "Received:" header with one of our IP addresses in it ?
Two things : First, check the email for any of our domains used in it.
If you have found our domain in the email, but it was not sent from any of our servers, please attach the file and send it as soon as possible to our abuse department, since it means someone from outside is abusing our services.
Secondly, look for the name "CustomerNews" and an unsubscribe link and a "click here if you cant read this mail" link inside your email. If you can't find those, it is probably a spam mail sent by someone else.
If there is anything suspicious in your mail neither ways, feel free to contact us and let us know about it so we may help you !
