;;Enter HELP ALL to see further discussion on all commands, or
;;HELP <command> to see further discussion of <command>.
;;
HELO ;;
;;The HELO command is used to identify the sending host to the receiver:
;;
;; HELO <domain>
;;
;; Where <domain> is the name of the sending host.
;;
;;If the receiver will accept mail, it responds with its name.
;;
;;The HELO command must be the first command of a mail sequence.
;;
MAIL ;;
;;The MAIL command is used after a HELO command to ask a receiver to
;;accept a mail message. The format is:
;;
;; MAIL FROM: <user>@<site>
;;
;;where <user> is the name of the user sending the message, and <site>
;;is the name of the site sending the mail, in Internet domain
;;format.
;;
;;The receiver will respond with "250 OK" if accepted, and "501 Invalid
;;Reverse path specification" if not.
;;
;;This command is followed with RCPT and DATA commands to name
;;and transfer the data, respectively.
;;
RCPT ;;
;;This command is used to identify the recipients of the mail.
;;Its format is:
;;
;; RCPT TO: <user>
;;
;;If the user is found, the receiver will respond with "250 OK";
;;Otherwise, it will say "501 Invalid forward path specification".
;;
;;Each recipient of the message is named individually. The VRFY
;;command can be used to confirm the existence of a user without
;;actually putting him on the recipient list.
;;After recipients are specified, the DATA command is used to transfer
;;the body of the message.
;;
DATA ;;
;;The DATA command is used after the MAIL and RCPT commands to transmit
;;the body of the message. The command has no arguments. The receiver's
;;response to the command is to either issue an error message:
;;"503 no recipients specified" or "354 Start mail input".
;;
;;Data will be accepted until a line consisting of a single period is
;;detected. If any line begins with a period, it must have an
;;additional period inserted at the beginning of the line.
;;
;;After the DATA command is completed, the receiver will respond with
;;"250 OK" if the message was accepted, or an error message if
;;otherwise.
;;
RSET ;;
;;The RSET (Reset) command is used to reset the receiver to its initial
;;state and cancel any mail in progress. The sender does not need to
;;issue HELO again.
;;
VRFY ;;
;;The VRFY (Verify) command is used to verify the existence of a user
;;at the receiver. The format is:
;;
;; VRFY <user>
;;
;;The computer will respond with the user's full name if found, or
;;"550 User not found" if not. This command can be issued at any
;;time, and does not affect the recipient list.
;;
EXPN ;;
;;The EXPN (Expand) command causes the receiver to expand a mailing
;;list, showing the sender the list of individuals in the list.
;;
HELP ;;
;;The HELP command displays user assistance information for interactive
;;users. If issued without an argument, it gives a general introduction.
;;If given an argument naming a command, it gives further information
;;on that command. If given an argument of "ALL", it displays
;;help on all arguments.
;;
NOOP ;;
;;The NOOP (no operation) command causes the receiver to respond with
;;a "250 OK" message.
;;
QUIT ;;
;;The QUIT command is used to terminate the mail transfer process.
;;The connection will be closed, and any mail transfers not concluded
;;with a successful DATA command will be lost.
;;
TURN ;;
