I'm using:
4 minutes
25 hours
92 days

In my experience, no legitimate mail server has retried to us in less 
than 5 minutes.  An unusual number of big ISPs do retry in 5 minutes.  
We retry in 5 minutes outgoing.  I have found that some significant 
mail servers retry once every 24 hours, sigh, hence the 25 setting. The 
last one is high because this is on a production server for paying 
customers... we want to minimize impact.
