delay-time

This command specifies the interval between polling sequences for the POP poller handler.

Syntax
delay-time seconds
Parameters
seconds
The interval in seconds between the polling sequences. Enter a value in the range 1 - 65535. The default value is 300.
Guidelines
The delay-time command specifies the time to wait after the completion of one polling sequence before the poller starts the next one. A polling sequence is the time to retrieve the messages plus the time to complete their processing.
Note: Some mail servers restrict the number of times an account can establish a connection during a specific time period. Make sure that the configured interval complies with any restriction.

Use the max-messages-per-poll command to set the number of messages to retrieve and process during a polling sequence.
