'Bounces'

[Brad H]

Just re-subscribed to cc-talk.  I'm wondering if anyone has an answer on
this - every now and again I get these warning emails about 'excessive
bounces'.  I have to click a link and then they go away for a while.  But
sometimes I get busy and forget.. and then the list unsubscribes me.  No
idea what 'excessive bounces' means or what I can do to prevent it from
unsubscribing.  Any thoughts?
