Spam: not dig a hole to another
Spam on the Internet - something commonplace and familiar to users and owners of popular resources. According to statistics, by 2012, more than 89% of all e-mails relating to falls or other characteristics to the category of "spam." At night automatically by mailing sent to 200 billion useless to anyone of e-mail, and started the company by e-mailing targeted bases 500-600.
If we consider the Russian part of the Internet market, he immediately percentage of spam e-mails just rolls, sometimes reaching 93% of the total number of messages. Daily produced up to 6500 mass mailings spam. These data can be considered only an estimate of the real situation.
Every hosting provider conducts its statistics, private antivirus developers have their own databases and surveys. All the pieces of information you can find on the net, but the official opinion of the spammers you are unlikely to find.
Fighting spam has started a couple of days after the launch of the first mailing. Can not be assumed that the methods used do not have the result. Spammers always just a second ahead.
One of the most popular technologies used by server administrators and sites is blacklisted, they also RBL-registers - realtime blackhole lists. In such registers are fixed IP-addresses, anyway associated with spam. To add to the list may result in compliance with one or more criteria:
- Sending spam from this IP-address or use it;
- This IP-address associated with your hosting provider on servers which is the site, advertising is seen in spam submissions.
These lists are compiled resource owners for their personal use, as well as in accordance with the policies adopted by the site. Any act of the Russian and international laws, this practice is not accountable.
There is also a classification blacklists registries I and II order. In the first list customized fixed IP-address, the second - IP-address block (and the group mesh) belonging to a specific provider. Then we can talk about certain marketing purposes of a resource in relation to the group owners IP-addresses.
To suit your needs, you can use the following resources to opening RBL-lists I order: Dul.ru, Dialup.blacklist.jippg.org, Spamsources.fabel.dk, Orbs.dorkslayers.com, Relays.ordb.org, Proxies.relays.monkeys . com, Formmail.relays.monkeys.com, Relays.mail-abuse.org and others.
Blacklists II order consists of the following sites: Spews.relays.osirusoft.com, Sbl.spamhaus.org, Work.drbl.mokr.ru, Block.blars.org, Relays.osirusoft.com and others.
It should be noted that using RBL-lists all different. While some users will see a warning in them and be able to fulfill the directive blocking then hosting providers mail servers access data lists each time upon receipt of one or other correspondence. In the case of IP-address of the sender in one of the registers of the letter will be forwarded back to the sender marked Prohibited by Administrator - Administrator is prohibited. The legitimacy of such actions - a topic for another discussion. Legally, such activity is at odds with federal law № 126-FZ "On Communications" determining integrity of the Network. Hosting provider is using someone blacklists filter information knowingly waives part of the e-mail coming from the web. Harmed by such policies as the server owner can users of the ISP (and often they are not aware of the application of such technologies to their inbox) and themselves to senders whose server was seen in connection with the blocked IP-addresses. Another victim is himself hosting provider sender receives angry letters on undelivered messages.
The reasonableness of the use of such information filters very controversial. Experts have repeatedly expressed a strong case against the use of blacklists. First, just because of the aforementioned problems with any innocent customers DNS-servers and users of IP-addresses hosting provider, trapped in such RBL-lists.
Secondly, the lists are often caught dynamic IP-addresses, involving change of ownership and valid for a specific customer only a short time. These are the ones used by professional spammers. Then blacklists simply do not make sense, because they can not catch a spammer on the spot.
Thirdly, RBL-lists suffer from poor work filtrator, which, depending on the personal benefit can work on multiple providers, leaving unwanted IP-addresses behind the list.
Fourth, spamming - a great example of black propaganda. Competitors successful site specifically inserted his name in large-scale spamming to reduce demand and sales closing IP-address of the owner.
Find guilty of spamming - the process time consuming and at times unhelpful. That spam is bad for business and the overall functioning of the Network - approval is not causing issues. Hosting providers have long made it a rule supporting the policy of quality customer service, to prescribe in terms of service principle of zero tolerance for spam and senders. Alas, it means only that seen in sending spam messages will be punished in accordance with paragraphs adopted the contracting parties, including to terminate the contract prematurely. It's clear that only through the adoption of common rules and compliance with technical conditions to achieve the complete elimination of spam server's life impossible. If your customers can still be monitored and punished, the other hosting users under these rules do not fall. Cases of unauthorized unconscious and spamming are also possible. Sender of the network provider. Catching the virus starts sending spam messages all over the web, advertising his personal Web site, located in the north of the same host. As a result, owners of RBL-lists link to get IP-address hapless spammer from hundreds or even thousands of users from all over the web. IP-address register includes hazardous and subject to the standard methods of combating spam. As a result, the owner of the resource provider receives from a torn contract and closed the site, and the owner of the hosting begins to deal with the consequences of such a careless mailing. A lot of effects, because at ignition of IP-addresses to blacklist all mail service, enjoying the registry cease to perceive explanatory letter from the victim host. Opravitel here and lose, and the recipient. Procedures to remove IP-addresses of all black lists that are multiplying like mushrooms, the provider may take more than one day. Gradually blocked not individual servers with the specified IP-addresses, and whole blocks. Negotiations and numerous explanations of what happened delayed for weeks. And more stubbornness manifested owners blacklists checking patience and perseverance owners affected hosting strength and provider users and customers on the level of anger.
It is useless to hope that resources are used in their work blacklists stop this thing. Part of postal services transferred this technology to combat spam level corporate policies and no longer responding to customer complaints on the illegality of such actions. There is another unpleasant minus in such methods of struggle: hoster until recently did not know about the complaints from users, and immediately gets checkmate in the form of appearance of their addresses on the blacklist. Facilitate the search for the true culprits infringing calm mailings as nobody tries. Understand the postal services is also possible, their business - communicating or not to deliver information to customers. But it is related to these processes hosting provider whose clients can not send emails to the filtered box? Yes, and how to respond to such methods - is unclear.
There are a few simple tips for hosting owners. If information about spam occurs, then the offender is notified to stop the actions of his account due to violation of rules associated with spam.
If the IP-address or a host address pool got blacklisted, the traditional way of life is changing dramatically provider. Technical support service begins a long and monotonous conversation with the owners RBL-lists. Prior to e-mail services to reach at this point is unrealistic. Reasonable to include only during the successful completion of the blacklist. As a consequence, filratory will not receive e-mail, hosting customers will swear letters, signs, and even many hours to dial in to the owners. With ISP clear - he will fight to the last, but what to do each individual customer - must be addressed individually.
The most common variant in this case - waiting for the end of negotiations with the owners of RBL-lists and receiving rehabilitation together with the return of the health post. The second way - to request a new mailbox on the mail portal that does not use RBL-lists, to continue to be in correspondence with customers and partners. Well, or you can once and for all solve this problem quickly - to put in a mail program SMTP-server of your host as SMTP-server. Then the mail will go directly to the recipient.
What can we improve the situation in the root? Of course, the adoption of the individual sections of the federal law prohibiting the sending of spam and increase fees for mailing, which today are piggy compared to a profit.
