Min reask delay
This option determines how often MLdonkey will re-query sources for the given file.
Default value for min_reask_delay is 600 seconds (10 minutes).
setting min_reask_delay to a smaller value may result in banning, for example from eMule clients. there is a rather long thread in the forum
pango writes there (030108): min_reask_delay is restricted to the 10 mins - 30 mins range by eMule peers (below: banning; over: lost queue rank), and a low min_reask_delay may be better for peers without an upload queue (edonkey, mldonkey), you don't have a lot of room for tweaking...
