What does residual bounce received mean in the bounce log file?

It means that the user's delivery was disabled by bounce processing and subsequent to that a bounce was received for that user.

This could be because the bounces for that user aren't returned until after some delay, but most of the time it's a bounce of the disabled warning sent to the user.
