Use this property page to configure basic Internet messaging with the GroupWise® Internet Agent.
SMTP and MIME are standard protocols for sending and receiving e-mail messages over the Internet. SMTP (Simple Mail Transfer Protocol) is the message transmission protocol. MIME (Multipurpose Internet Mail Extension) is the message format protocol.
Enable SMTP Service
Turn on this option to allow Internet
messaging. SMTP service is on by default.
Number of SMTP Send Threads
Select the number of threads you want used by the Internet Agent to send messages.
The default is 8 threads. This setting corresponds with the Internet Agent's /sd switch.
Number of SMTP Receive Threads
Select the number of threads you want used by the Internet Agent to receive
messages. The default is 16 threads. This setting corresponds with the Internet
Agent's /rd switch.
Kill Threads on Exit or Restart
Select this option to cause the Internet Agent to stop immediately, without
allowing its send/receive threads to perform their normal shutdown procedures.
This setting corresponds with the Internet Agent's /killthreads switch.
Enable iCal Service
Select this option if you want the Internet Agent to be able to convert outbound
GroupWise Calendar items into MIME text/calendar iCal objects and to convert
incoming MIME text/calendar messages into GroupWise Calendar items. This setting
corresponds with the Internet Agent's /imip switch.
Hostname/DNS "A Record" Name
Specify the Internet hostname of the server where the Internet Agent resides,
or the name of the "A record" in your DNS table that associates a
hostname with the server's IP address. You should have received a hostname
from your Internet service provider. This setting corresponds with the Internet
Agent's /hn switch.
If the Reject Mail if Sender's Identity Cannot Be Verified setting (SMTP/MIME tab > Security Settings page) is selected, you are required to fill in the Hostname/DNS "A Record" Name setting. When a TCP/IP communication begins, the two servers involved exchange greetings. Part of the greeting requires the recipient server to identify itself. The other part of the greeting requires the sending server to identify itself with the SMTP HELO command. The Internet Agent verifies the authenticity of the greetings. If the greeting string does not match the actual Hostname/DNS "A record," the Internet Agent either passes a warning and continues the communication or terminates the connection.
If you leave this field blank, the Internet Agent uses the fully qualified hostname obtained from your Internet service provider (such as xyzcompany.com), which you should have entered in the Foreign ID field on the Identification page (GroupWise tab).
Relay Host for Outbound Messages
If you want to use a relay host, or smart host, to route all outbound Internet
e-mail, specify the IP address, or DNS hostname, of the smart host. The smart
host can be part of your network or can reside at the Internet service provider's
site. You can list multiple relay hosts by using a space to separate each hostname
in the list. This setting corresponds with the Internet Agent's /mh switch.
Scan Cycle for Send Directory
Specifies how often the Internet Agent polls for outgoing messages. The default
is 10 seconds. This setting corresponds with the /p switch.
Use 7 Bit Encoding for All Outbound Messages
By default, the Internet Agent uses 8-bit MIME encoding for any outbound messages
that are HTML-formatted or that contain 8-bit characters. If, after connecting
with the receiving SMTP host, the Internet Agent discovers that the receiving
SMTP host cannot handle 8-bit MIME encoded messages, the Internet Agent converts
the messages to 7-bit encoding.
With this option selected, the Internet Agent will automatically use 7-bit encoding and not attempt to use 8-bit MIME encoding. You should use this option if you are using a relay host that does not support 8-bit MIME encoding.
Maximum Number of Hours to Retry a Deferred Message
Specify the number of hours after which the Internet Agent stops trying to send
deferred messages. The default is 96 hours (4 days). A deferred message is any
message that couldn't be sent because of a temporary problem (host down, MX
record not found, and so forth). This setting corresponds with the Internet
Agent's /maxdeferhours switch.
Intervals to Retry a Deferred Message
Specify in a comma-delimited list the number of minutes after which the Internet
Agent retries sending deferred messages. The default is 20, 20, 20, 60. The
Internet Agent interprets this list as follows: It retries 20 minutes after
the initial send, 20 minutes after the first retry, 20 minutes after the second
retry, and 60 minutes (1 hour) after the third retry. Thereafter, it retries
every hour until the number of hours specified in the Maximum Number of Hours
to Retry a Deferred Message field is reached. You can provide additional retry
intervals as needed. It is the last retry interval that repeats until the maximum
number of hours is reached. This setting corresponds with the Internet Agent's
/msgdeferinterval switch.
Return Notification to Sender When a Message Is Delayed
Select this option to provide e-mail notification when a message is delayed
and cannot be sent out across the Internet. This provides more noticeable notification
to users than manually checking the Properties page of the sent item to see
whether it has been sent.
Do Not Publish GroupWise Information on an Initial SMTP Connection
This option suppresses the GroupWise version and copyright date information
that the Internet Agent typically responds with when contacted by another SMTP
host or a telnet session. It is enabled by default. This setting corresponds
with the Internet Agent's /nosmtpversion switch.
