internet!domain!user
So if your address were nancyr@world.std.com, your correspondent would send a message to you at
internet!world.std.com!nancyr
Bitnet
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 izzy%indvyvms.bitnet@cunyvm.cuny.edu 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
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: 73727.545@compuserve.com. 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 form:
>INTERNET:YourID@YourAddress.
For example, >INTERNET:adamg@world.std.com. Note that both the ">" and the ":" are required.
