Hi Len,

Please excuse the late post regarding your issue.  I would like to make
available an Imail Access Control List file that contains about 130,000 IP's
that we are seeing doing massive dictionary attacks.  We had to create the
list for ourselves just to manage connection overloads.  This list is
updated hourly and has really cleaned our DHA issues and our server is back
to normal.  If you would like to try it please email me directly.

Thanks in advance.
