Our mail server runs on a mac cube with OS 9.1.  For the past few months various companies have been refusing our email due to an SBL from http://relays.osirusoft.com/ which claims we might be spammers (we're not).

Osirusoft says that we have been added to their list because of a

"Wide-open _anonymous_ HTTP proxy on port 8000"

but I have no idea how to close the port or make it secure.

Can anyone help me shut the port (and tel lme how to get us off the SBL at the same time) ?

Have a look at your firewall settings on your router. Port 8000 open?

I'll have to ask the ISP who supply our bandwidth since we come through their router - they're a big company so I wouldn't have thought so, but worth trying.  Thanks.

I've spoken to our ISP and they have confirmed that it is our machine which has the open port.

It seems they are right - you can telnet to our mail server on port 8000,type \'GET http://www.google.com/ HTTP/1.0\' and press enter twice to get the google front page.

TBH, I know nothing about mac netowrking, so any help on closing this port would be much appreciated.

You've got a router between the cube and your net connection right? Use it's firewall to close port 8000.

On  a PC you'd be looking for the service that is active and listening on port 8000 - and then make sure you stop that service. Isn't there a similar action to take on a Mac? Or even to look through the services that *should* run, for any kind of misconfiguration, like using port 8000 and change the config.

Just being curious here...

Yeah, you could dig through you apps and do stream sniffing to see what is using which ports, or you could just close port 8000 and be done with it.

Found it - one of db team had installed a plug-in to webstar which opened 8000.  Removed it and then shut the port.

Not sure how to allocate the points - 50 each to rid and weed ?

Cheers
