Creating and sending mail
You can use the mail program to create, send, reply, and forward messages to other users or to send ASCII files to other users.
An ASCII file might, for example, be a document you have written using a preferred editor or a source file for a program.
You can send messages and files to a user on your local system, on your network, or to a user on another connected network. The recipient does not need to be logged on to the system when you send the information. Mail is sent to a user's address.
