In some instances, the remote systems that you post leads to would fail for reasons that may seem unlikely i.e. an Internal Server Error.  For such errors you have the option to automatically retry posting the lead to ensure that you do not miss out on selling your leads.  In this video you can see how to set this up.

Points to note:

1. You can set how many times you want to auto-retry
2. You can set the interval time to auto-Retry i.e. every 5 mins.
3. Auto-Retry does not work as part of Advance Distribution i.e. Priority, Weighted Distribution
