Which method should I choose?
Aside from the slight difference in pricing, this is an important decision. Many mail servers already support RBL style lookups directly out of the box, or have an easy way to add RBL lists, so it is very simple to setup and configure, and that is why it is one of the supported methods. However the BMS™ system has some definite advantages.
RBL Technology requires that your email server does a DNS lookup for every connection to resolve the IP address, and using our RBL server, which you will gain access to once you have arranged a registration, is very fast. However, it does add some load to your DNS servers. As well, if there is a problem with DNS for any reason, the results can vary from mail server to mail server, but it can range from not providing protection, to failure to deliver messages, depending on your implementation.
If for any reason, our main RBL servers go offline, or gets hit by a DDOS attack, then the RBL lookups may fail.
If you are using a mail server technology that doesn't support RBL, this may not be an option for you.
BMS Technology on the other hand, (BMS is a LinuxMagic Patent Pending Technology) allows instantaneous lookups against locally cached data. This means, that even if the DNS is offline, you are protected by the latest snapshot.
With our technology, your servers will be downloading a highly compressible binary data set of all the IP and Network information from our main repository, every hour or every day, depending on your requirements. This data set will be uncompressed locally on your server and the BMS Client will be used to check this data to see if an IP Address is listed.
For certain mail servers, the BMS Policy Daemon will check that cached data. This allows more flexibility, and even allows you to integrate it into other technologies, which may allow you to have user-definable rules, rather than server-wide rules.
