Yes, this is two deliveries, for two recipient records in the queue
file, that are in fact the same recipient address? Why does this
message have to identical envelope recipients? The pipe(8) pid
would be the same for a single delivery with two recipients, as
would "delays".

So do any other messages deliver multiple recipients together via

What is the address class of the recipient domain (etl.qa.agari.com)?
What configuration settings result in the use of the pipe transport?
