To view the "Queues" statistics in the "Monitor Pane", click on the "Queues" tab. Use this tab to determine how messages efficiently Spamphibian Gateway is processing messages that are to be delivered destination SMTP servers or bounced back to senders.

Spamphibian Gateway has three queues: incoming queue, outgoing queue, and the retry queue. Once a message has been received, it is placed in the incoming queue until it can be run through the various rules and filters. If the message is to be delivered to the destination SMTP server, it is placed in the outgoing queue. Bounce messages and delivery failure notices are also placed in the outgoing queue and Spamphibian Gateway will attempt to deliver them in a "first in, first out" method. If Spamphibian Gateway is unable to deliver a message, it will be placed into the retry queue until it is appropriate to retry to deliver the message. To determine the maximum number of messages that were in incoming, outgoing and retry queues during a given interval, move your mouse over the interval in the chart. To change a color for a queue type, click on the color next to the label for that queue type in the legend and use the color wheel to select a new color. The vertical axis on the right hand side of the chart corresponds to the number of messages in the queues.

To determine the average process time during a given interval, move your mouse over the interval in the chart. Spamphibian Gateway keeps track of how much time passed between when a message arrived and when it was successfully delivered it to the destination SMTP server. The average process time appears as a line graph on top of the queue bars. To change the color for the average process time line graph, click on the color next to the "Average Process Time" label in the legend, and use the color wheel to select a new color. The vertical axis on the left hand side of the chart corresponds to the average process time.

Many factors effect the average process time, including Spamphibian Gateway's various SMTP Out settings and the responsiveness of the destination SMTP server. To learn how to change your SMTP Out settings to reduce your average process time, see the "SMTP Out Settings" section of "Chapter 7: Advanced Spamphibian Gateway Administration".

Note: The time it takes to process bounce, delivery failure, quarantined, rejected, blocked, and purged messages will not affect the average process time statistic. This statistic is provided only to determine if "Accepted" messages are being efficiently delivered to the destination SMTP server.
