I have a client that uses spamdyke but I am new to it. I've read through the documentation so I am vaguely familiar with it now. They have been under a DDOS attack for about a month now. It's not enough to bring their servers down. Basically it's a bunch of SMTP traffic attempting to send spam. Spamdyke has been doing a great job of blocking the connections usually with the DENIED_RDNS_MISSING error. The problem is this attack has been eating up a lot of their bandwidth. As a temporary measure their ISP has asked them to just drop the invalid connections instead of issuing the appropriate SMTP response codes. Is this something spamdyke can be configured to do? I did not see anything obvious in the documentation.
