Configuring SpamRATS on Communigate
How to configure SpamRATS RBLs on Axigen MTA
In the Communigate PRO mail server, the SpamRATS RBL protection can be configured through the Admin interface:
http://
After accessing the Admin Interface, Navigate to Settings -> Services -> SMTP -> Security.. Look for DNS Blacklists and check 'Enable DNS Blacklists'
In the RBL Configuration, add the RBL's you want to use one item per line.
[YOUR_API_KEY].spam.spamrats.com
[YOUR_API_KEY].dyna.spamrats.com
[YOUR_API_KEY].noptr.spamrats.com
You can choose to Reject, Tag, or Log Only. Remember to commit and then test. Normally though, we want to make sure that ONLY the correct response is treated as being on the list. For instance, 127.0.0.36 for RATS-DYNA. Any other IP returned should NOT be treated as being on the list. It could be a rejection error.
Using SpamRats RATS-AUTH to prevent Email Compromise
(INFORMATION MISSING, Please help out). Everyone should use RATS-AUTH to protect their authentication layers, including POP/IMAP/SMTP(25,465,587) and WebMail. You can even use it to protect other logins on your server.
Warning: Please remember that you MAY not be able to query from some DNS servers, especially without an API key. You should use a DNS servers that clearly identifies who is making the query (PTR Record). Consider using your own local resolver if you have troubles. With a subscription, there are alternative ways to get data.
Caveats and Testing that it Works
RBL's work using DNS, and you should ALWAYS look for the correct IP Address being returned. Simply getting a "result" doesn't always mean the IP is listed. It should return the specific IP address, anything else might mean an error, and should be ignored and NOT rejected. Also, your DNS needs to be able to correctly query our mirrors. Bad firewall rules that prevent you from reaching our mirrors, means that you are not protected. You can always test at the command line first. A simple..
host 36.0.0.127.[YOUR_API_KEY].dyna.spamrats.com host 1.0.0.127.[YOUR_API_KEY].dyna.spamrats.com
.. the first example should work and return 127.0.0.36, while the second example should return NXDOMAIN. (IP Not found). If that doesn't work, check your firewalls first, and check which DNS servers you are using, and finally test/check your API key is correct, and active before reaching out to us for support.
