Further update...

I have had to close down the SMTP Port 25 for a few hours to hope these people go away!


I forgot to add these details:

I am:

= Sendmail 8.14.1/8.14.1
= MailScanner 4.66.5

Also... my Snort system has registered... over 7000 "(portscan) Open Port: 25" entries in the last 2 hours!  From these IPs.

210.59.228.42
210.59.228.65
210.59.228.93
210.59.228.113
