55 E-Mail SMTP Outbound Server

The Oracle Message Transfer Agent uses the SMTP Outbound Server to route mail.

55.1 Messages

This category contains metrics that provide information on the receipt and delivery of e-mail messages.

55.1.1 Distribution List Message Reception Rate (Messages/minute)

This metric represents the number of distribution list messages received per minute by the SMTP Inbound and Outbound Servers.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
All Versions	Every 10 minutes

55.1.2 Message Transmission Rate (Messages/minute)

This metric represents the number of messages the SMTP Outbound Server transmitted per minute to local or foreign Message Transfer Agents for the purpose of mail delivery.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The Consecutive Number of Occurrences Preceding Notification column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 55-1 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold'	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every 10 Minutes	After Every Sample	>	1000	1500	1	SMTP outbound message transmission rate: %value% messages/minute

User Action

Check the server logs to make sure that your server is not being used as an open relay. If a sender is flooding the server, considering adding this sender to the list of blocked IP addresses. Use esd_logscan.pl to scan the server log files.

55.2 Network

This category contains metrics that provide information about network resources used by an SMTP Outbound Server. Information includes the amount of data the server sent out and information about network connections.

55.2.1 Current SMTP Outbound Connections

This metric represents the number of socket connections to foreign or native Message Transfer Agents that the SMTP Outbound Server currently has opened for the purpose of relaying mail delivery.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The Consecutive Number of Occurrences Preceding Notification column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 55-2 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold'	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every 10 Minutes	After Every Sample	>	200	250	1	The current outbound SMTP connections are %value%

User Action

Check the logs for connections to certain destinations that are slow in responding. Check the destination mailstore SMTP and Oracle Collaboration Suite Databases for any resource constraints. Also, check the logs to make sure that your server is not being used as a open relay.

55.2.2 Data Transmission Rate (Kb/minute)

This metric measures the number of kilobytes transmitted per minute by the SMTP Outbound Server to local or foreign Message Transfer Agents over socket connections for the purpose of mail delivery.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The Consecutive Number of Occurrences Preceding Notification column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 55-3 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold'	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every 10 Minutes	After Every Sample	>	100000	125000	1	SMTP outbound data transmission rate: %value% Kb/minute

User Action

Check the server logs to make sure that your server is not being used as an open relay. If a sender is flooding the server, considering adding this sender to the list of blocked IP addresses. Use esd_logscan.pl to scan the server log files.

55.2.3 SMTP Outbound Connection Rate (Connections/minute)

This metric represents the rate of connections opened per minute by the SMTP Outbound Server to deliver mail to a local or foreign Message Transfer Agent.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The Consecutive Number of Occurrences Preceding Notification column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 55-4 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold'	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every 10 Minutes	After Every Sample	>	2000	2500	1	The SMTP outbound connection rate is %value% connections/minute

User Action

Check the server logs to make sure that your server is not being used as an open relay. If a sender is flooding the server, considering adding this sender to the list of blocked IP addresses. Use esd_logscan.pl to scan the server log files.

55.3 Response

This category contains metrics that provide information about the Up/Down status of the SMTP Outbound Server.

55.3.1 Status

This metric provides information about the Up/Down status of the SMTP Outbound Server and alerts you when the status is Down. The SMTP Outbound Server shows a status of Down when all processes on the host are down.

Metric Summary

The following table shows how often the metric's value is collected and compared against the default thresholds. The Consecutive Number of Occurrences Preceding Notification column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

Table 55-5 Metric Summary Table

Target Version	Evaluation and Collection Frequency	Upload Frequency	Operator	Default Warning Threshold'	Default Critical Threshold	Consecutive Number of Occurrences Preceding Notification	Alert Text
All Versions	Every 10 Minutes	After Every Sample	>	0	Not Defined	1	No SMTP OUT server running

User Action

You can start the SMTP Outbound Server by selecting the target and clicking theStart button on the Email Application home page. If the SMTP Outbound Server does not start, a probable cause is that the server cannot connect to at least one of the Oracle Collaboration Suite Databases or it cannot connect to the system's Oracle directory server.

1. Check that a process on the target host is able to connect to and log into the system's Oracle directory server.

2. Make sure the Oracle Collaboration Suite Database is up and running and the connect string is correctly and accurately registered in the Oracle directory server.

3. Check the log files in the OPMN log file directory for errors. Use esd_logscan.pl to scan the log files.

4. Check the SMTP Outbound Server log files for errors. Use esd_logscan.pl to scan the server log files.
