I like the exponential delay but something like 5% extra instead of 50% might be better. Otherwise in just one day, you are going to have massive retry delays. Plus 1 query per hour = 24 queries a day versus over 100K per day. I think 1 per hour is going to be a really good number to start with and won't need much modification. -- Configure bugmail: https://issues.apache.org/SpamAssassin/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
