What happens to bounced leads when they are sync'd from Zoho CRM? Plus a few other questions related to sync'ing.

A few questions for the MH team.

I've a list of leads that come form a sync to a ZohoCRM view. 

1.  What happens when a sync'ed lead is bounced.  Does the bounce information get pushed back into the CRM?  If so, when and what does that look like?

2.  If a lead upsubscribes, what happens to the sync'ed contact in the CRM?

3.  When I delete a lead from MH, can I re-sync the lead (so it is no longer deleted)  from the ZohoCRM contact?
