20 ;;This is the simple mail transfer protocol receiver
21 ;;Commands currently understood are:
22 ;;HELO <domain> (which initiates a transaction)
23 ;;MAIL FROM: <reverse-path>
24 ;;RCPT TO: <forward-path> (which names a recipient)
25 ;;DATA (terminated with a single line of '.')
26 ;;HELP (which displays this text)
27 ;;NOOP (which does nothing)
28 ;;RSET <reason for> which stops transmission of message
29 ;;STAT (which displays the current status of the receiver)
30 ;;VRFY <user> (which verifies the existence of a user)
31 ;;TURN (Which turns around the line; Sender becomes receiver)
32 ;;EXPN <mail group> (which lists the members of a group)
33 ;;QUIT (which terminates the connection)
34 ;;
35 ;;CHRS <domain> initialize a remote domain
36 ;;Extensions:
37 ;;MESS ID:XMREMID Sending message remote ID to allow processing to stop
38 ;;
39 ;;Enter HELP ALL to see further discussion on all commands, or
40 ;;HELP <command> to see further discussion of <command>.
41 ;;
42HELO ;;
43 ;;The HELO command is used to identify the sending host to the receiver:
44 ;;
45 ;; HELO <domain>
46 ;;
47 ;; Where <domain> is the name of the sending host.
48 ;;
49 ;;If the receiver will accept mail, it responds with its name.
50 ;;
51 ;;The HELO command must be the first command of a mail sequence.
52 ;;
53MAIL ;;
54 ;;The MAIL command is used after a HELO command to ask a receiver to
55 ;;accept a mail message. The format is:
56 ;;
57 ;; MAIL FROM: <user>@<site>
58 ;;
59 ;;where <user> is the name of the user sending the message, and <site>
60 ;;is the name of the site sending the mail, in Internet domain
61 ;;format.
62 ;;
63 ;;The receiver will respond with "250 OK" if accepted, and "501 Invalid
64 ;;Reverse path specification" if not.
65 ;;
66 ;;This command is followed with RCPT and DATA commands to name
67 ;;and transfer the data, respectively.
68 ;;
69RCPT ;;
70 ;;This command is used to identify the recipients of the mail.
71 ;;Its format is:
72 ;;
73 ;; RCPT TO: <user>
74 ;;
75 ;;If the user is found, the receiver will respond with "250 OK";
76 ;;Otherwise, it will say "501 Invalid forward path specification".
77 ;;
78 ;;Each recipient of the message is named individually. The VRFY
79 ;;command can be used to confirm the existence of a user without
80 ;;actually putting him on the recipient list.
81 ;;After recipients are specified, the DATA command is used to transfer
82 ;;the body of the message.
83 ;;
84DATA ;;
85 ;;The DATA command is used after the MAIL and RCPT commands to transmit
86 ;;the body of the message. The command has no arguments. The receiver's
87 ;;response to the command is to either issue an error message:
88 ;;"503 no recipients specified" or "354 Start mail input".
89 ;;
90 ;;Data will be accepted until a line consisting of a single period is
91 ;;detected. If any line begins with a period, it must have an
92 ;;additional period inserted at the beginning of the line.
93 ;;
94 ;;After the DATA command is completed, the receiver will respond with
95 ;;"250 OK" if the message was accepted, or an error message if
96 ;;otherwise.
97 ;;
98RSET ;;
99 ;;The RSET (Reset) command is used to reset the receiver to its initial
100 ;;state and cancel any mail in progress. The sender does not need to
101 ;;issue HELO again.
102 ;;
103VRFY ;;
104 ;;The VRFY (Verify) command is used to verify the existence of a user
105 ;;at the receiver. The format is:
106 ;;
107 ;; VRFY <user>
108 ;;
109 ;;The computer will respond with the user's full name if found, or
110 ;;"550 User not found" if not. This command can be issued at any
111 ;;time, and does not affect the recipient list.
112 ;;
113EXPN ;;
114 ;;The EXPN (Expand) command causes the receiver to expand a mailing
115 ;;list, showing the sender the list of individuals in the list.
116 ;;
117HELP ;;
118 ;;The HELP command displays user assistance information for interactive
119 ;;users. If issued without an argument, it gives a general introduction.
120 ;;If given an argument naming a command, it gives further information
121 ;;on that command. If given an argument of "ALL", it displays
122 ;;help on all arguments.
123 ;;
124NOOP ;;
125 ;;The NOOP (no operation) command causes the receiver to respond with
126 ;;a "250 OK" message.
127 ;;
128QUIT ;;
129 ;;The QUIT command is used to terminate the mail transfer process.
130 ;;The connection will be closed, and any mail transfers not concluded
131 ;;with a successful DATA command will be lost.
132 ;;
133TURN ;;
134 ;;
