You probably remember our articles on how to pick a platform for reseller hosting business and Reseller billing software comparison. As we continue the series of useful articles for resellers, the next thing we are going to talk about is domain reselling.

What Does It Work For?

Domain reselling business is to some extent easier to run than hosting reselling, and because of this many people choose to conduct this business. The advantage is obvious – unlike a hosting reseller, you don’t need to administer anything but the name servers (in most cases only once – after the domain purchase) and you are not supposed to resolve any technical problems, as there can hardly be any. What you need to do is just watch them being updated on time.

Taking into account the latest trends of services unification, it becomes understandable that in order to attract more customers a company should provide a range of services. Thus, to become a successful hosting reseller you also need to provide domain reselling. Your clients will be really glad to realize that they can pay for several services using one client area. Additionally, this will make things easier for both you and them in terms of support – you will be able to manage your customers’ domains.

How It Works?

Domain reselling is a special service, offered by domain registrars. The idea of this service is to increase the domain sales by attracting new registrants not directly, but through a reseller. This idea became very popular since domain reselling is more profitable for both the registrar and the reseller, than an affiliate program, which is not that easy to manage, considering the amount of domains sold annually.

Being resellers, registrants are able to control all their resold domains under their own accounts and to set custom prices. Branding is allowed as well. Branding option may be useful, if a simple reseller wants to become a featured one or even a domain investor. Usually, domain resellers choose a range of TLDs they are going to offer. Usually, the so-called popular TLDs: .COM, .NET, .ORG, .INFO, .BIZ. Domains with such TLDs used to have a floating price on the market and considering the discounts, the registrars provide their resellers with, the latter can make a good profit out of it. Additionally, being a domain reseller, a hosting reseller can make such marketing moves as free domain provision for the top hosting plan.

Summary

Reselling is a nice small business solution for those who do not have their own platform to start an own independent company. Such business, however, is a perfect launch pad, so it should be organized so, that it would look professional. We hope, that tips we publish will help you with improvement of your business. Next time we are going to bring out more ideas on how to improve your reseller business, as it may grow into a standalone company one day.

Ever since Internet became available to the public and started being used on commercial purpose, the problem of SPAM emerged. There are many types of spamming – via e-mail, through instant messengers, even by posting forum threads or replies and blog comments. Today we are going to tell about ways of fighting the most irritating type of spam – e-mail spam.

What is SPAM? Ways It Works, Impact It Makes

E-mail spam a.k.a. unsolicited bulk e-mail (UBE) started spreading in the early 90’s. Since most spam messages have commercial content, it is also called unsolicited commercial email (UCE). SPAM is usually sent through zombie networks (or botnets) – networks of virus or malware-infected computers. And if UCE just irritates the mailbox owner by the fact of its delivery, fraudulent or virus-containing spam may cause bigger problems – credit card information leaking, password and other security data loss or even making the recipient’s computer another zombie.

Nowadays all Internet, web hosting and public e-mail services providers have a ruling in their Terms of Services and Acceptable Use Policies (TOS/AUP) regarding outgoing spam delivery prohibition. Spammers cause much abuse, as the complaints sent to the administrators of the servers, where bulk mailers are located, may lead to the servers’ IP addresses getting into an IP blacklist. In some cases, when the complaints are multiple and the spammer cannot be taken out (sometimes it is really hard to trace and locate a spammer on the server) – the server may get null-routed. If it is a shared server, (spammers usually choose non-expensive shared plans to perform a “one-shot” bulk mail delivery or spam until the account is suspended/terminated) – it is usually a disaster for a hosting company, because when an IP address gets blacklisted – it may take up to a week to have it “delisted”. Now imagine how much time it will require for the upstream provider (datacenter) to review the null-route removal request (not counting the time required for the investigation).

User-end Spam Protection Measures

It is obvious that server administrators need to take strict security measures to avoid any outgoing spamming attempts. But what about the incoming spam? Sure, anti-spam systems and filters used on the servers do not accept spam messages, but the rules set in there cannot be too strict, since it is a shared server and you simply cannot tell who really deals with online pharmacy and who is being spammed by some creepy offers. That’s where the user should take additional measures.

When talking about user-end means of spam prevention we first of all mean native control panel tools. There are two of them.

SpamAssassin

SpamAssassin is an open source spam filter, compatible with such mail services as procmail, sendmail, Postfix and qmail. Being easy to extend and to configure, it gets perfectly built into almost any hosting control panel. Below you can find the snapshots of DirectAdmin and cPanel-driven SpamAssasin tool:

General View and Main Options of cPanel-based SpamAssassin

As you can see, both panels provide a little bit different interfaces and configuration options, however both have two main options we are to describe: blacklisting and “spam score” assignment.

The former option is the one to take out all the messages from a given domain (*@domain.com) or a separate mailbox under it (user@domain.com). It is recommended to use, if you are constantly receiving targeted spam from some organization. They may be just harmless newsfeeds but have no unsubscribe option, which is rather irritating. Thus, you either lock out the entire domain or a particular account (in case you are interested in getting some useful information from other mailboxes).

The “spam score” assignment option works in a different way. It passes all incoming email through with no blocks, but analyzes each of them. The analysis covers the email content: subject, headers, body (for spam-keywords, attachments, html-code, etc.). Once the set score is reached, the email is discarded and moved to the spam folder. This allows the user to analyze why the email was labeled as spam and either blacklist or whitelist it. SpamAssassin does have a sad drawback though – it cannot be “trained” to keep email addresses in memory, so that those messages, which constantly get into the spam box, could be sorted and then automatically blacklisted.

Manual Email Filtering

What cannot be done with the help of SpamAssassin, can be easily done manually by means of a control panel. Creation of additional filters will not only grant you better spam protection, it will also let you trace the most active outgoing addresses. This in turn allows to blacklist those addresses and lessen the load on your server – if the email is rejected by default, the system consumes less server resources, than for its content analysis.

Email filters in different control panels have different sets of options. Apart from the entire domain and single account filtering, all of them are able to filter e-mail subject and body. Depending on the configuration, some may filter by message size and others – by headers or added recipients (CC, BCC).

Report Spam

Public e-mail services like Gmail or Yahoo! provide their users with spam reporting options. This is very useful, since depending on the number of complaints on a single account/domain the strictness of measures to take varies. Your hosting provider may not provide you with such an option, but who says you are unable to report spam on your own? There are many Real-Time Block Lists (RBL blacklists) on the Web, two of them, however, are the most trusted and recommended for use – SpamCop and SpamHaus. Both services accept unofficial spam reports, so you should not experience any problems – just provide their team with as much information as possible. Namely, you need to provide the email address, domain and IP the spam was received from, and attach or better paste the subject of the spam mail you received together with headers and email body (but do not just forward the spam message).

Besides escaping spam delivery from the reported domains/IPs, you will help others, since once the spammer gets blacklisted, other servers which perform RBL block checks for incoming emails will stop receiving spam from those email and IP addresses as well.

Bottom Line

When hosting services users complain on incoming spam to their support team and server administrators, they usually receive a reply, that it is almost impossible to get a 100% spam protection. Some people get irritated when they hear it, but it really is true – server administrators cannot set too strict filtering rules, while spammers are becoming more and more sophisticated at bypassing the existing ones. The user-side actions, however, are able to increase this rate, so if our article assists you to reach a 99.9% spam protection rate, you make consider the spam-fighting mission accomplished.
