Thank you, Chip.  Here's more info... 
 My application is written in FoxPro and  running in a Windows environment on AWS.  Users connect via a Remote Desktop Connection.  So, everything (including Blat) is running on Amazon's server; nothing is running on the user's computer.  I think my client's IT dept is ok, but maybe we're wondering about the collective minds of the IT dept of the client's email server provider.
 

 In my configuration, am I using Amazon's DNS server?  Does it cache?  And do I have any control over whether it is caching?
