| Since early hours of Oct 31, our mail server is experiencing mail flood from
a variety of IP addresses spread throughout the world. The mails are coming
to anyname@ourdomain.com. Thus our server is receiving them as domain name is
valid. However they are building up in the queue for directory lookup as the
names are invalid. Yesterday, we received about 3500 emails per hour. The
rate has come down to about 20 per minute since we rebuilt our denied IP
address list.
What else can we do to stop this siege on our mail server?

| Hi Sgupta,
you might want to have a look at www.aloaha.com.
Our Proxy is exaclty what you need since it will not allow that flood coming
in.
Kind Regards
Frank Hellmann
