My application on an AWS server has been successfully sending emails using BLAT for a long time.

Each of my users has a different email server (whatever they use for themselves separately from my application is what they use for my application).

Just one of my many users occasionally runs into an error. Their email server's tech support has asked me if I can have my program start using a "caching DNS."

Here's where I am naive. I don't know what this means, I don't know if I'm already using a caching DNS, and I don't know how to implement this.

Can you advise me?

Thank you... Art Lieberman
