This page is to inform both our customers and the general public what is being done to combat the growing issue of spam emanating from wholesale suppliers in the wake of the enormous growth of our business. If you have a need to report a spammer, please do so by sending as much detailed information about the offender as possible to the following address:
Our staff will take your complaints very seriously and do all they are able to in any way to eliminate the originator of the UCE violation.
Spam is a problem that is beginning to have a serious impact on the continued success of the Maranatha service and our customers. Due to the overwhelming growth of the Wholesale Dial-up market there has been an unfortunate expansion of spam originating from these Wholesale Dial-up ports. With hundreds of ISPs utilizing the Wholesale services to expand their national footprint, the likelihood of a spammer signing up with an ISP using the Wholesale services is rapidly increasing.
The way spam is typically sent has continually evolved as new ways to combat and block it have been developed. The current trend in sending spam employs software that runs over a dial-up connection and connects directly to the mail port of the target. This is the hardest to block because it doesn't pass through any "mail relay" servers, on which anti-spam filters could be employed. The target has difficulty in stopping the attack without also blocking other legitimate mail from coming through. Once a spammer is identified, the account can be quickly identified and terminated.
However, due to the success of the internet and the ISP market, many accounts can be obtained on a trial basis for little or no money, accounts can be activated over the phone with falsified information, and other tricks can be used to gain a "throw-away" account. ISPs can combat the proliferation of spam accounts, but due to market pressures, most do not scrutinize each account to ensure that it is not going to be used to spam. The further a company is from dealing with the individual end-users, the harder it becomes to scrutinize new accounts. It is not realistic to expect this of every ISP, and even when such monitoring is done, it cannot completely prevent this type of spam from being sent. Careful monitoring merely stops spammers from being able to spam with free accounts. Some would argue that once spammers are hit in the wallet, they would mend their ways and move on to something else. That is not likely to occur.
This is the issue facing Maranatha today. There are too many spammers using too many "throw-away" accounts to continue to attempt to combat the problem. Therefore, we have implemented a proactive solution that helps to resolve this problem.
The Problem Defined
Mail uses TCP port 25 for sending and receiving mail between servers. Spam software either connects directly to TCP port 25 on the mail servers being targeted, or routes its mail though Open-Relay servers (mass email marketers call these "email friendly off-shore servers"). Because it connects either directly or indirectly in this fashion it is extremely difficult for the target server to block the incoming spam.
Blocking port 25 is extremely easy to do, but one problem with blocking port 25 is that once done, legitimate users can no longer send email because they cannot connect back to their ISP's mail server. Maintaining a single filter to allow access back to each Wholesale customer's mail servers is not a scalable solution. Assuming that each ISP has a minimum of two mail servers, and factoring in the fact that there are already thousands of ISPs, there could be several thousand lines in the access list. Add in the fact that some ISP's have more than two mail servers, and that some Wholesale customers are in turn reselling the Wholesale service to yet more ISPs, and you suddenly have an extremely long and complex filter, a filter that has to be updated every time an ISP is added to the various Wholesale services, leaves the services, or has to change its server's IPs. This is not a viable option.
Our solution is to apply global filters to our mail servers. Global filters are able to read the headers of incoming mail, and decide whether or not that mail contains enough criteria to warrant rejecting the message or not. Filters can be based on the name or IP address of the server connecting, the email address of the sender, the email address of the receiver, what is contained in the subject line, the contents of the body of the message or any combination of the above.
Filtering has been extremely successful in blocking quite a bit of spam, but it is not enough. Spam continues to come from Open-Relay servers, and once identified, are blocked at our router and can no longer enter our network. The vast majorities of these servers do not have a reverse DNS entry and are easily identifiable. Maranatha also uses an RBL (Real Time Black List) that blocks known Open Relay servers.
Maranatha wants to work with all of our customers to make this process as comprehensive to the end-users as can be. We welcome any feedback that you may have regarding this solution. Please contact us at email@example.com with any questions or comments you may have.
