採用[1.1.1.1]為主機名的垃圾主機
最近有些廣告信採用為主機名，當然封鎖主機名 [* ，就可以阻擋了，但是下面這個本主機居然還一直試，真是給它OOXX，不知道有沒有直接可以給它停止連線的方法。<br><br>Tue 2006-05-30 13:50:55: ---------- Partial transcript, remainder will follow. <br>Tue 2006-05-30 13:50:55: Session 6855; child 1; thread 640 <br>Tue 2006-05-30 13:50:22: Accepting SMTP connection from <br>Tue 2006-05-30 13:50:22: Performing PTR lookup (46.227.252.222.IN-ADDR.ARPA) <br>Tue 2006-05-30 13:50:23: * Error: Name server reports domain name unknown <br>Tue 2006-05-30 13:50:23: * No PTR records found <br>Tue 2006-05-30 13:50:23: ---- End PTR results <br>Tue 2006-05-30 13:50:23: --> 220 cfwater.com.tw ESMTP MAIL ready <br>Tue 2006-05-30 13:50:23: <-- EHLO <br>Tue 2006-05-30 13:50:23: --> 250-company.com.tw Hello , pleased to meet you <br>Tue 2006-05-30 13:50:23: --> 250-ETRN <br>Tue 2006-05-30 13:50:23: --> 250-AUTH=LOGIN <br>Tue 2006-05-30 13:50:23: --> 250-AUTH LOGIN CRAM-MD5 <br>Tue 2006-05-30 13:50:23: --> 250-8BITMIME <br>Tue 2006-05-30 13:50:23: --> 250 SIZE 0 <br>Tue 2006-05-30 13:50:24: <-- MAIL FROM:<[email protected]> <br>Tue 2006-05-30 13:50:24: --> 550 Domain company.com.tw does not accept mail from <br>Tue 2006-05-30 13:50:24: <-- RSET <br>Tue 2006-05-30 13:50:24: --> 250 RSET?
