This is the statistics of entry-path of the mail flood got from the received mails headers. fgwmail 83 fgwnews 82 fgwmail5 45 fgwmail6 31 ------------------- total 241
count(fgwmail) = count(fgwnews) =near count(fgwmail5) + count(fgwmail6)
In your above scenario, why hundreds of duplicated mails are delivered? If deliveries to fgwmail5/fgwmail6 always succeed, the duplicated mails should be not more than 3 or so. Is it wrong?

I asked to the admin of fgwmail/fgwnews to investigate the machine status and I forwarded your analysis of them.
I'll report thier investigation result when I get.

It's your nice CGI script.. I also tried but he claimed nothing.
BTW, what do you mean "not acknowledged"?
