Hi, <br />
<br />
We have a virtual web server with many websites in there, we suspect that the server could be banned in a Blacklist but first of all, there are hundreds of Blacklists servers, so how could we perform an exhaustive search? Is there some kind of big list that includes all of them? <br />

Any recommendations? <br />

Thanks.

Hi, 

We have a virtual web server with many websites in there, we suspect that the server could be banned in a Blacklist but first of all, there are hundreds of Blacklists servers, so how could we perform an exhaustive search? Is there some kind of big list that includes all of them? 

Any recommendations? 

Thanks.

how to perform an exhaustive Blacklist search?

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

Web Servers

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.
