That's easily taken care of. Instead of a cron-job, you could have a script running as a daemon, checking for emails to be sent every 5mins.

That's the same as running a cron every 5 minutes except now you also need to detect if your daemon dies :) On the plus side though, you eliminate the overhead of starting up the script every 5 minutes :)

It is not the same as it will prevent multiple scripts running concurrently in case a batch of emails takes longer that 5 minutes. Checking if the daemon dies - I guess it's a matter of taste or paranoia, but I don't think it's necessary when the script is sufficiently simple: #!/bin/sh while true do

    <yourscript>
    sleep 300

done

I accomplish the same with cron scripts by using locks with expiry.

got an example? my cat skinning skills need to be improved, the cat won't like it but screw the cat, right?
