Finding
Mail Addresses
You can learn the electronic mail address
of another person by asking him or by using one of the following resources:
-
A postmaster at the recipient's organization
can provide the correct address when you know the the domain name of the
organization. Send a message requesting help to postmaster@domain.
-
The DDN Network Information Center (DDN NIC)
in Menlo Park, California, maintains a "white pages" directory of computer
users, hosts, and domains on the Internet. You can use Telnet to access
this database on a computer called nic.ddn.mil. Many computers also have
a program called whois, which automatically accesses the DDN NIC database.
Ask your system administrator whether your computer has whois.
-
Network interest groups include bulletin boards
("bboards") and mailing lists. Messages are distributed to people who share
an interest but may not know each other.
-
Three important, organized sources of interest
groups are available to people who can exchange mail with the Internet:
Internet mailing lists, BITNET LISTSERV, and USENET news. There is a lot
of overlap between them. Each Internet mailing list has a moderator or
coordinator. You must ask to be put on the list by sending an electronic
mail message to the moderator. Internet mailing lists are not highly automated.
The only problem is how to distinguish the moderator from the list.
-
A list of Internet mailing lists (about five
hundred kilobytes in size) is available by anonymous FTP from the Internet
host nisc.sri.com at SRI International, Menlo Park, California. Use these
commands:
-
cd netinfo
-
get interest-groups
-
BITNET LISTSERV is a highly automated program
that automatically sends electronic mail messages and subscribes and unsubscribes
users in response to formatted messages. LISTSERV programs run on many
BITNET hosts. A subscribe message can be sent to any LISTSERV programQit
will be forwarded to the correct host. For a complete list of LISTSERV
lists, send the command list global to any LISTSERV.
-
Telnet is a program that allows a computer
user at one site to work on a computer at another site. It is the Internet
standard protocol for remote terminal connection service. Telnet requires
Internet access (that is, you must be on a network that gateways to the
Internet). Unlike FTP and electronic mail, telnet exposes you to the commands
and programs of the remote host. For example, you can use the telnet command
to run a program in your directory on a supercomputer hundreds of miles
away.
