Sorry, this is a totally incorrect explanation of what sendmail queue 
groups are.

There is not a QUEUE_GROUPS single parameter that says how many ways to 
split a message.

There are ways to define multiple queue groups, and then, to define the 
maximum number of recipients per envelope for any message delivered via 
that queue.
