What command can identify processes running on ports?

I have just installed SLES 8. I run netstat -a and see there is a process listening on the smtp port.

I need to kill this process as it is preventing me from starting James email server (James is complaining about smtp address already being used).

Therefore, what command can I run to identify the process listening on port 25? Once I have identified this process, I will stop it from starting when the machine is rebooted.

Thanks in advance.

Use the -p option to netstat or use lsof and grep for the port.

"netstat -ap" did the trick. Thanks very much.
