My ISP just fingered me as an open relay. I'm not really happy about this. I've done research on sendmail in general, and have noticed that Cobalt has a really insecure version of sendmail running - 8.10.2
I have followed the instructions provided by my isp on fixing this (basically editing my access file) and it still failed. I've used the relay-test.mail-abuse.org test and come back solid, as in ok, no relay. Heres the transcript of the test they used, and the error that went through. Any ideas on how to secure this?
Any help appreciated.
Here's the output of the entire session:
telnet 192.168.0.1 25
