Checking to see if a mail server is on a Black Hole list

To find the IP address of a mail server:

    In a DOS prompt windows, type

1. nslookup, enter. 
2. set type=mx
3. domain.ext (type in the email domain)

In a web browser, go to njabl.org and type in the mail server IP.

For the in-house list, go to Cypher.  There's an icon on the screen.

To check the mail logs for anti-spam

1. go to cypher.
2. Folder on the desktop for "Logs"
3. Find the date and double-click on the log with extension SL
4. Search for the email address.

Email logs:

1. SM contains all the mail received by our server, including ones it rejected.  Look for the IP address of the sending server.
2. SL contains all the mail rejected by our server.

To add to the exceptions list:

• Go to Cypher
• On the desktop, there's an icon for Exceptions
• Enter the IP address backwards, and make sure you change the date (sequence number) at the top.
• Reload the DNS.

In a DOS prompt window:

nslookup (the mail server's IP address backwards).relays.ordb.org

nslookup (the mail server's IP address backwards).relays.osirusoft.com

If either of these returns the address 127.0.0.2, you're on the list.

example:  if the IP address is 206.154.151.190:

nslookup 190.151.154.206.relays.ordb.org

For the in-house list, go to Cypher.  There's an icon on the screen.
