Remote DoS

[davi]

Hi Guys,

Anyone aware of a remote DoS against qmail?
We we're attacked this weekend and attackers were able to crash SMTP without 
affecting any others services in the machine.
This was _not_ the multiple RCPT TO: problem.
I run qmail 1.03 + qmailqueue patch + qmailscanner under tcpserver limiting 
memory resources to 7 MB.
