SMTP TEST AND SCENARIO DESCRIPTIONS
This section provides a description of each SMTP Scenario
objective and an operational description of each test's
verification procedure.
Scenario r_basic
Scenario r_basic is the first scenario of an SMTP test session.
This scenario tests the Receiver-SMTP Implementation Under Test
(IUT) for basic mail reception and the compliance of the IUT
Remote Driver (RD) to the DCA Protocol Laboratory SMTP Remote
Driver Specification. If the IUT and the RD do not produce good
results on the first run of this test scenario, then further
testing should be abandoned until the problems are corrected.
In scenario r_basic the Central Driver (CD) commands the
Laboratory Driver (LD) to mail a message to the IUT. The CD then
verifies the receipt of the message by commanding the RD to read
the IUT's mail queue and send the results back to the CD using
the RD spool command. The CD verifies that the correct command
responses and mail message were received.
TEST 1: BASIC MAIL RECEPTION (RECEIVER-SMTP)
Does the IUT correctly receive a mail message and store it in its
mail queue?
ACTION: The CD establishes a connection with the IUT. The CD
conducts a basic mail transaction (HELO, MAIL, RCPT, DATA, QUIT)
sending a message containing a unique message identification
number. The RD reads the IUT mail queue and sends back the mail
message to the CD in a Test Scenario Language (TSL) data packet.
VERIFICATION: The CD searches the contents of the TSL data
packet for the correct command replies and message identification
(id) number.
SUCCESS: The correct command replies and message id are found.
FAILURE: Any of the following indicates an IUT failure:
Connection not made;
Incorrect command replies received;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
Message id is wrong or nonexistent.
Scenario s_basic
Scenario s_basic tests the Sender-SMTP IUT for basic mail
transmission capability. If the Sender-SMTP IUT and RD do not
produce good results on the first run of this test scenario, then
further testing should be abandoned until the problems are
corrected.
12 March 1987 -8- Unisys Corporation
TM-WD-8801/610/01
In scenario s_basic the CD commands the RD to place a mail
message with a known message identification number on the IUT's
queue. The mail message is addressed to the Reference Receiver
SMTP at the Protocol Laboratory. The Sender-SMTP IUT should start
a mail transaction and send the message. The CD confirms the
receipt of the message by reading the laboratory mail queue. The
CD verifies that the correct mail message was received by
searching for the known message identification number.
TEST 2: BASIC MAIL TRANSMISSION (SENDER-SMTP)
Does the IUT Sender-SMTP correctly format and transmit a mail
message?
ACTION: The CD establishes a connection with the IUT. The CD
commands the RD to place a mail message with a unique id number
on the IUT mail queue. The Sender-SMTP IUT should find the
message in the queue and start a mail transaction. The mail
message is sent to the Reference Receiver-SMTP. The Reference
places the message on the Lab mail queue. The CD commands the LD
to spool the mail message. The LD passes the mail message,
including the id number, to the CD in a TSL data packet.
VERIFICATION: The CD searches for the correct command sequences
and the correct message id number.
SUCCESS: The correct command sequences and message id are found.
FAILURE: Any of the following indicates an IUT failure:
Connection not made;
Command sequences are incorrect;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
Message id is wrong or nonexistent.
Scenario r_helomulti
Scenario r_helomulti tests the Receiver-SMTP IUT capability to
correctly process multiple HELO commands after the start of a
mail transaction.
TEST 3: MULTIPLE HELO COMMANDS DURING TRANSACTION
Does the IUT correctly process multiple HELO commands after the
start of a mail transaction?
ACTION: The CD establishes a connection with the IUT. Multiple
HELO commands are issued, followed by a QUIT command.
12 March 1987 -9- Unisys Corporation
TM-WD-8801/610/01
VERIFICATION: The CD searches for the correct command replies.
SUCCESS: The CD receives a command reply of 250 for each HELO command.
FAILURE: Any of the following indicates an IUT failure:
Command replies of 500, 501, 504, or 421;
Command replies other than those listed above;
Connection not made;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses.
Scenario r_multircpt
Scenario r_multircpt tests the Receiver-SMTP IUT capability to
process multiple RCPT commands during a mail transaction.
TEST 4: MULTIPLE RCPT COMMANDS DURING A TRANSACTION
Does the IUT correctly process multiple recipients?
ACTION: The CD establishes a connection with the IUT. The CD
first sends the HELO and MAIL commands. Then the CD sends
multiple RCPT commands.
VERIFICATION: The CD searches for the correct command replies.
The CD also checks the mail queue for multiple mail messages.
All messages should be received with the correct message id
number.
SUCCESS: CD receives a command reply of 250 or 251, and all
messages are received with the correct message id.
FAILURE: Any of the following indicates an IUT failure:
Command error reply of 500, 501, 503, 421
received;
Command failure reply of 550, 551, 552 553 450
451, or 452 received;
Connection not made;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
A message id is wrong or nonexistent.
Scenario r_send
Scenario r_send tests the Receiver-SMTP IUT capability to process
the SEND command. The CD commands the LD to send a mail message
with a known identification number to the destination IUT's
terminal screen (not to a mailbox). The tester must verify the
correct receipt of the message by manually checking the terminal
screen.
12 March 1987 -10- Unisys Corporation
TM-WD-8801/610/01
TEST 5: SEND COMMAND DURING A TRANSACTION
Does the IUT correctly process the SEND command?
ACTION: The CD establishes a connection with the IUT. The CD
commands the LD to issue the SEND command with a known message
identification number. The message is displayed on the
destination terminal screen.
VERIFICATION: The CD searches for the correct command reply and
receives manual verification of correct message receipt at
destination terminal. Also, no mail message should have been
spooled onto IUT mail queue.
SUCCESS: The CD receives a command reply of 250, a manual
verification of message receipt, and no mail message is found on
IUT mail queue.
FAILURE: Any of the following indicates an IUT failure:
Command failure reply of 552, 451, or 452;
Command error reply of 500, 501, 502, or 421;
Mail message found on IUT mail queue;
Connection not made;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
Message id is wrong or nonexistent.
Scenario r_sendbad
Scenario r_sendbad tests the Receiver-SMTP IUT capability to
process the SEND command with an undeliverable destination
address. If the IUT offers SEND service, then the CD commands
the LD to send a mail message to the IUT. The message will
always be undeliverable since the message will be addressed to a
test user who would not be logged on. Therefore, the IUT should
notify the CD of an undeliverable message.
TEST 6: SEND COMMAND WITH AN UNDELIVERABLE ADDRESS
Does the IUT correctly process undeliverable mail using the SEND
command?
ACTION: The CD establishes a connection with the IUT. The CD
commands the LD to send a mail message to a nonexistent user.
VERIFICATION: The CD searches for the correct error reply to the
RCPT command (the RCPT command is used in conjunction with the
SEND command).
SUCCESS: The CD receives an error reply of 550 or 421.
12 March 1987 -11- Unisys Corporation
TM-WD-8801/610/01
FAILURE: Any of the following indicates an IUT failure:
Command success reply of 250, or 251 received;
Command error reply of 500, 501, or 503 received;
Command failure reply of 551, 552, 553, 450, 451, or 452;
Connection not made;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
Message id is wrong or nonexistent.
Scenario r_soml
Scenario r_soml tests the Receiver-SMTP IUT capability to process
the SOML command. The CD commands the LD to send or mail a mail
message with a known identification number to the destination
IUT's terminal screen or mailbox. If the message does not get
placed onto the IUT mail queue, then the tester must verify the
correct receipt of the message by manually checking the terminal
screen.
TEST 7: SOML COMMAND DURING A TRANSACTION (RECEIVER-SMTP)
Does the Receiver-SMTP IUT correctly process the SOML command?
ACTION: The CD establishes a connection with the IUT. The CD
commands the LD to issue the SOML command with a known message
identification number. The message is either displayed on the
destination terminal screen or placed onto the IUT mail queue,
but not both.
VERIFICATION: The CD searches for the correct command reply and,
if the message was not placed onto the IUT mail queue, receives
manual verification of correct message receipt at destination
terminal. Also, no mail message should have been placed onto the
IUT mail queue if the message was displayed at the destination
terminal.
SUCCESS: The CD receives a command reply of 250, a manual
verification of message receipt at destination terminal, and no
mail message is found on IUT mail queue; or, a 250 reply with no
message received at the destination terminal, but a correct
message placed onto the IUT mail queue.
FAILURE: Any of the following indicates an IUT failure:
Command failure reply of 552, 451, or 452;
Command error reply of 500, 501, 502, or 421;
Connection not made;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;

Scenario s_longline
Scenario s_longline tests the Server-SMTP IUT capability to
correctly process an excessively long reply line.
TEST 43: EXCESSIVELY LONG REPLY LINE
Does the IUT correctly process reply lines exceeding the allowed
512 bytes?
ACTION: The CD establishes a connection with the IUT. The CD
command the RD to place a message with a known message
identification number onto the IUT mail queue. The CD commands
the Reference Receiver-SMTP to listen for a connection attempt
from the IUT. The Sender-SMTP IUT should find the message in the
queue and initiate a mail transaction with the Reference
Receiver-SMTP. The Reference Receiver-SMTP replies correctly to
the connection opening and the HELO command, but replies
incorrectly to the MAIL command. The IUT should attempt to reset
the connection with the RSET command and then complete the mail
transaction.
VERIFICATION: The CD searches for the correct commands and the
correct message id number.
SUCCESS: The CD receives the correct commands and the correct
message id number.
FAILURE: Any of the following indicates an IUT failure:
Connection not made;
Incorrect commands received;
RD does not correctly interpret CD commands, or
acknowledge CD commands, or format IUT responses;
Message id is wrong or nonexistent.
