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:
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
