Can I trigger mail retrieval from the command line?

Yes. Use the POPconTrigger utility included with POPcon:

popcontrigger SERVERNAME

Replace SERVERNAME with the name of the computer running the POPcon service. This triggers an immediate mail retrieval cycle.

You can call this from batch files, task schedulers, or any script. It is useful for triggering mail checks on demand rather than waiting for the next scheduled interval.
