Hello, I have recently discovered that ordb.org has listed us as an open relay. I found the following in my logs: 05:23 14:25 SMTPD(0A8300A8) [64.94.14.60] connect 64.94.14.62 port 4693 05:23 14:25 SMTPD(0A8300A8) [64.94.14.62] EHLO sm2.mail.king.com 05:23 14:25 SMTPD(0A8300A8) [64.94.14.62] MAIL FROM:<spamtest@[64.94.14.62]> 05:23 14:25 SMTPD(0A8300A8) [64.94.14.62] RCPT To:<[EMAIL PROTECTED]> 05:23 14:25 SMTPD(0A8300A8) [64.94.14.62] e:\Imail\spool\D5e360a8.SMD 1118 05:23 14:25 SMTP-(00000274) processing e:\Imail\spool\Q5e360a8.SMD 05:23 14:25 SMTP-(00000274) Trying marvin.ordb.org (0) 05:23 14:25 SMTP-(00000274) Connect marvin.ordb.org [62.242.0.190:25] (1) 05:23 14:25 SMTP-(00000274) 220 groundzero.ordb.org ESMTP Postfix 05:23 14:25 SMTP-(00000274) >EHLO mx2.cooking.com 05:23 14:25 SMTP-(00000274) 250-groundzero.ordb.org 05:23 14:25 SMTP-(00000274) 250-PIPELINING 05:23 14:25 SMTP-(00000274) 250-SIZE 10240000 05:23 14:25 SMTP-(00000274) 250-ETRN 05:23 14:25 SMTP-(00000274) 250 8BITMIME 05:23 14:25 SMTP-(00000274) >MAIL FROM:<spamtest@[64.94.14.62]> 05:23 14:25 SMTP-(00000274) 250 Ok 05:23 14:25 SMTP-(00000274) >RCPT To:<[EMAIL PROTECTED]> 05:23 14:25 SMTP-(00000274) 250 Ok 05:23 14:25 SMTP-(00000274) >DATA 05:23 14:25 SMTP-(00000274) 354 End data with <CR><LF>.<CR><LF> 05:23 14:25 SMTP-(00000274) >. 05:23 14:25 SMTP-(00000274) 250 Ok: queued as CC29C5B117 05:23 14:25 SMTP-(00000274) rdeliver marvin.ordb.org [EMAIL PROTECTED] (1) <spamtest@[64.94.14.62]>�1118 05:23 14:25 SMTP-(00000274) >QUIT 05:23 14:25 SMTP-(00000274) 221 Bye 05:23 14:25 SMTP-(00000274) finished e:\Imail\spool\Q5e360a8.SMD status=1 What does it take to block this type of exploit?
