Internet Email Search

Tasks, tools and methods for finding e-mail addresses

Main tasks:

  • white-search e-mail addresses of a specific person;
  • white-search e-mail addresses of a specific organization;
  • white-search e-mail addresses in a specific organization;
  • white-search for an e-mail address of a host;
  • reverse white-search for a subscriber by e-mail address;
  • yellow-search e-mail address of the organization.
  • special case: search for e-mail addresses of educational institutions and their students;

To search for e-mail addresses of people, organizations and network nodes, the Netfind help service (available on-line) and automatic address servers of the Whois type (available both on-line and by e-mail) are specially designed. They also fill in their address bases automatically, constantly and in bulk directly from the address bases of large network nodes (or search directly in them), which contain a fairly complete set of records about their subscribers.

Basic search tools:

  • Netfind automatic help desk
  • automatic address servers such as Whois;
  • automatic address servers of other types;
  • Yellow pages help systems containing e-mail addresses.

Additional search methods:

  • special requests to the automatic servers of a mass service (newsgroups or mailing lists) or any other way to obtain a list of its subscribers;
  • a request to subscribers of any mass service;
  • a request to the host network personnel;
  • a request to an automatic address server or to the staff of an organization that provides public access to the addresses of its correspondents (customers, partners, etc.).

Netfind help desk

Netfind on a single request performs a white search in many address databases and other help services. To use this service, you need to have the Netfind client program on your computer; in its absence, you can use telnet (logname "netfind") on any of the Netfind servers in the world:

In addition, Netfind is available through the WWW server:

Whois server

Whois-servers perform white-searches in large databases of addresses of large nodes or entire networks. Work with whois-server occurs according to certain rules (whois-protocol), therefore it is advisable to use a special client program (whois-client). In UNIX, such a program is called: whois, it can be given the address of any of the whois-servers to search on it. Whois servers are also available via telnet.

telnet: // mailto: HELP

Reverse Email Search (Finger)

The Finger search service allows you to find a specific person by their full e-mail address. You can use it while in the UNIX operating system and look for subscribers on other UNIX machines (since the Internet consists of them). Finger can show the registration name of the subscriber on the remote machine (login name), some important data about him, if he indicated them (name of the organization or unit where he works and his phone), as well as the time he last read his email (you can determine whether he still uses his e-mail address). Many UNIX machines have a finger server that accepts requests not only about specific e-mail addresses, but also allows you to do various searches among your users.

X.500 help desk

The X.500 Global Reference Service brings together local reference services that look like one large hierarchical directory. Access requires a special program (local X.500 client), but if it is not, then you can use any of the available public remote X.500 clients in the world, which can be accessed via telnet, through some Gopher and WWW servers, and even via e-mail:

Yellow Pages Systems

On the Yellow Pages, classifications are usually used according to occupation, by product and service rendered, by geographical feature. Sometimes they are supplemented with white-search (just alphabetically).

A search engine is a cross between Yellow and White Pages (he calls himself White Pages). It searches for people not only by its own name, but also by country, city, state, domain, hobby. On the server you can leave information about yourself.
