maximal_queue_lifetime = 1h

will do that. One hour is pretty short though if there's a problem along the way

As Billymayday implies, you probably shouldn't fool with the queue lifetime. Adding delay to the notify_classes parameter might be of interest to you.

Edit: I just saw that you're using 2.1. Not sure if my advice applies to that version.

thanks for your help!! billy and berhanie :-)
