The mail/rmail Utility
You can use mail, the mail user agent to compose and send messages to
users. The mail command, when used without arguments, displays all
the messages, with the last received message displayed first. For each
message, mail prints a ? prompt, and reads a line from the standard
input to determine the disposition of the message. mail exits
automatically when the last message is displayed. It provides a set of
command-line options to alter the messages being printed.
You can use the command mail -e to check for new mail messages. You
can also edit the mailfile to alter the functioning of mail. For example,
you can include the following line in mailfile to forward all mail
addressed to the owner to a given machine or person:
Forward to <person>
This is used especially for forwarding mail to a given machine in a
multiple-machine environment. The Forward option requires read-write
group permission and mail group ID in the mailfile.
Unlike mail, you can use rmail only to send messages. UUCP uses rmail
as a security precaution.
For more information on mail and rmail, type man 1M mail at the
HP-UX prompt.
