Yes, I think we are all trying to understand unfortunately this question
gets ignored.
I have gotton responses on the MSExchange forum but other than adding
another layer of protection I haven't found anything.
But most important I want to be sure no one is actually getting through and
it's just a lot of reporting going on.
I also have not heard if anyone has had success on changing port numbers
(posted on ftp forum).
I have read it is difficult to get it to work properly but supposedly can be
done. This of course includes working with a firewall.
Thanks for responding.
