Sorry, I should have been clearer in my question. What I wanted to know is what does it run? Why is it run ever two minutes? How does this affect the running of Gossamer Mail?
A cron job can basically run anything. The cron file can include any number of cron jobs. Each line in the cron file is a different cron job, that can be set to run something at a specific time(s), on a hourly, daily, weekly, monthly etc schedule.
With gossamer mail you're simply adding a new cron job that runs the gossamer mail collection script every two minutes.
You could equally have another cron job that runs a rebuild on your LinkSQL directory once a day at 11.00pm.
Hope that helps?
