     There are a number of computer networks that are not directly
part of the Net, but which are now connected through "gateways" that
allow the passing of e-mail.  Here's a list of some of the larger
networks, how to send mail to them and how their users can send mail to
America Online
     Remove any spaces from a user's name and append "aol.com," to get
     America Online users who want to send mail to you need only put
your Net address in the "to:" field before composing a message.
     Address your message to user@attmail.com.
     From ATTMail, a user would send mail to you in this form:
     So if your address were nancyr@world.std.com, your correspondent
would send a message to you at
     Users of Bitnet (and NetNorth in Canada and EARN in Europe) often
have addresses in this form: IZZY@INDVMS.  If you're lucky, all you'll
have to do to mail to that address is add "bitnet" at the end, to get
izzy@indvms.bitnet.  Sometimes, however, mail to such an address will
bounce back to you, because Bitnet addresses do not always translate
well into an Internet form.  If this happens, you can send mail
through one of two Internet/Bitnet gateways. First, change the @ in
the address to a %, so that you get username%site.bitnet.  Then add
either @vm.marist.edu or @cunyvm.cuny.edu, so that, with the above
example, you would get izzy%indyvms.bitnet@vm.marist.edu or
      Bitnet users have it a little easier: They can usually send mail
directly to your e-mail address without fooling around with it at all. 
So send them your address and they should be OK.
     CompuServe users have numerical addresses in this form:
73727,545. To send mail to a CompuServe user, change the comma to a
period and add "@compuserve.com"; for example:
     Note that some CompuServe users must pay extra to receive mail from
the Internet.
     If you know CompuServe users who want to send you mail, tell them
to GO MAIL and create a mail message. In the address area, instead of
typing in a CompuServe number, have them type your address in this
     For example, >INTERNET:adamg@world.std.com.  Note that both the
">" and the ":" are required.
     To send mail to a Delphi user, the form is username@delphi.com.
    To send mail to people using a Fidonet BBS, you need the name
they use to log onto that system and its "node number.''  Fidonet node
numbers or addresses consist of three numbers, in this form:
1:322/190.  The first number tells which of several broad geographic
zones the BBS is in (1 represents the U.S. and Canada, 2 Europe and
Israel, 3 Pacific Asia, 4 South America).  The second number
represents the BBS's network, while the final number is the BBS's
"FidoNode'' number in that network. If your correspondent only gives
you two numbers (for example, 322/190), it means the system is in zone
     Now comes the tricky part. You have to reverse the numbers and
add to them the letters f, n and z (which stand for
"FidoNode,''"network,'' and "zone'). For example, the address above
would become
     Now add "fidonet.org'' at the end, to get
f190.n322.z1.fidonet.org. Then add "FirstName.LastName@', to get
Note the period between the first and last names. Also, some countries
now have their own Fidonet "backbone" systems, which might affect
addressing.  For example, were the above address in Germany, you would
end it with "fido.de" instead of "fidonet.org."
     The reverse process is totally different. First, the person has
to have access to his or her BBS's "net mail" area and know the
Fidonet address of his or her local Fidonet/UUCP gateway (often their
system operator will know it).  Your Fidonet correspondent should
address a net-mail message to UUCP (not your name) in the "to:" field. 
In the node-number field, they should type in the node number of the
Fidonet/UUCP gateway (if the gateway system is in the same regional
network as their system, they need only type the last number, for
example, 390 instead of 322/390).  Then, the first line of the message
has to be your Internet address, followed by a blank line.  After
that, the person can write the message and send it. 
     Because of the way Fidonet moves mail, it could take a day or two
for a message to be delivered in either direction.  Also, because many
Fidonet systems are run as hobbies, it is considered good form to ask
the gateway sysop's permission if you intend to pass large amounts of
mail back and forth. Messages of a commercial nature are strictly
forbidden (even if it's something the other person asked for). Also,
consider it very likely that somebody other than the recipient will
read your messages.
      To send mail to a GEnie user, add "@genie.com" to the end
of the GEnie user name, for example: walt@genie.com.
      To send mail to somebody with an MCIMail account, add
"@mcimail.com to the end of their name or numerical address. For
     Note that if there is more than one MCIMail subscriber with that
name, you will get a mail message back from MCI giving you their names
and numerical addresses. You'll then have to figure out which one you
want and re-send the message.
     From MCI, a user would type
                Your Name (EMS)
at the "To:" prompt.  At the EMS prompt, he or she would type
followed by your Net address at the "Mbx:" prompt.
     To send mail to a Peacenet user, use this form:
     Peacenet subscribers can use your regular address to send you
     UserID@prodigy.com.  Note that Prodigy users must pay extra for
Internet e-mail.
