Where are docs on bounce handling?

I must have missed this somewhere in my reading about SmarList. Could someone tell me where to find the documentation on how SmartList handles email that bounces because of incorrect email addresses, full mailboxes, etc. I'm looking for something more than the schematic overview in section 3m of the Manual. Thanks for your help pointing this out. -Kevin Zembower ----- E.
