Hello Customer,
Thank you for posting here.
From your post, I understand that your server is listed in CBL.
First of all, I recommend you to contact the CBL's contactor to check the
exact reason why you've been added to the list.
In addition, besides the server, I suggest you also check the client
workstations to see if there is any spam and virus.
If there's any update or you have further concerns, please don't hesitate
to let me know.
Best regards,
Manfred Zhuang(MSFT)

| We are still having problems with the CBL, we were listed again over

|
| The CBL does NOT list for open relay - I found this out this morning.
| They do say:
|
| You have a virus, or an open proxy, a trojan spam-sender or some other
| sort of security compromise, or some sort of unusual misconfiguration
| which is causing your IP to be relisted.
|
| Is there an easy way to detect these issues on SBS?
