In that case, they are probably real, legitimate bounces of bad
addresses. The hard failures have probably all been disabled by now.

If they only started today, I don't know what the issue might be. There
is a bug in the Python email library that can cause problems if you have
a lot of bad addresses. See <http://bugs.python.org/issue5713>.

But that shouldn't be the issue here. I don't have a clue what the
'Address already in use' message means. Check your MTA's logs. Also see
the FAQ at <http://wiki.list.org/x/-IA9>.
