Just noticed my server was listed in CBL blacklist. I am not sure why as the server is at my home and there are only 2 workstations in my network. I run virus scan on each pcs and didn't find any virus and spyware. One thing I remember is that i did some telnet test and tried to send some test mail from the domain I don't own to the problematic domain address.
ex: let's say my domain is abc.com, but when I do telnet, i did
Telnet mail.bb.com 25
Did this cause my ip listed in blacklist? and i also did some open relay test.
ex: my domain is abc.com
rcpt to: email@example.com
Are any of the above caused me to be listed in blacklist??
