1. Check that your mail server is not an open relay 2. Monitor connections to your server's port 25 from within the network. Try wireshark for SMTP traffic On 28 January 2011 13:31, boniface njoroge <bonifacenjoroge5@gmail.com>wrote:

What type of connection are you on. Do you get a public IP via DHCP? Do you have a mail server. You can check the logs if Logging is enabled. Alternatively, scan computers for viruses. Your gateway is also a good place to sniff for unusual smtp traffic. On Fri, Jan 28, 2011 at 1:33 PM, Simon Mbuthia <simon.mbuthia@gmail.com>wrote:

Hello Boni, If you have a mail server on your network, then the best thing for you to do is to enable detailed logging for SMTP sessions. Coupled with knowledge of your network (how IPs are used by your LAN hosts) it becomes very easy to figure out if it is your server that is compromised or one of the hosts on your LAN. All other answers you will receive are wild shots:) -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!
