Default | 1 (minute) |
Description
According to the HCL product documentation:
This setting specifies the time (in minutes) that the Agent Manager delays before scheduling a new mail-triggered agent after new mail is delivered. The default is 1 minute. … The delay time ensures the agent runs no more often than the specified interval. When the agent executes, it will also process all additional events (if any) that occurred during the interval.
With
AMgr_NewMailEventDelay, the Domino server controls how quickly an "On New Mail" agent actually starts after a new mail arrives. Longer delay → the agent runs less frequently (relieves the server); shorter delay → the agent reacts faster (more load). On each run, all accumulated mails are processed together.Example configuration
AMgr_NewMailEventDelay=1
Notes & pitfalls
- Value in minutes.
- Complementary to
AMgr_NewMailAgentMinInterval(minimum interval between two runs of the same agent).
- A setting of
0does not eliminate the delay completely — according to HCL, a built-in minimum interval remains.
- Longer intervals reduce CPU/IO load on servers with high mail volume.
