Subject: [Christmas Gift for free] 50% Spam reduction !

Hi,

introducing a delay in qmail-smtpd EHLO greeting by about 30 secs will
reduce the amount of spam emails by typically 50%.

In case you believe it or even if don't believe it, use my 5 line patch
for qmail-smtpd.c available here:

For the german reading community follow that URL:

Actually, I couldn't believe it by myself; but it works high efficient.

regards and merry x-mas.
--eh.
