In the simplest terms, the email domain is the web address that comes after the @ symbol in an email address. For example, in [email protected], “company.com” is the email domain. These follow particular constraints, and unlike the email prefix (the area in front of the @ symbol) can’t be  easily modified for vanity. The email domain must match the requirements of the host name. It should consist only of letters, digits, hyphens and dots.

While most businesses will have such suites in place, it often falls to the email service to provide an additional layer of anti-phishing and anti-malware protection. Our reviews found a surprising variance in this department, however, ranging from very robust to completely non-existent, so be careful. Since it's such a huge liability for business owners, this could be one of the most important factors in terms of background features. At the very least, it's better than filing an insurance claim or outright losing funds due to simple social engineering tactics. 

When creating a custom email address, think of it the same way you would when creating a new website. First, you pick an email platform to use, then you point your domain name to it. For example, if “The Dude”—fictional owner of theinternet.io—wanted to set up a custom email address, he would search through the email hosts in our plugins page and pick the one that he likes best.
A personalised email address on your domain like [email protected] increases the value and perception of the professionality of your business to customers and prospects. While free email services offered by Google, Yahoo, etc. are fine for personal use, a custom email address will prove that you are a professional or legitimate business. If you already have a hosting plan with one.com, your personalised email address comes as part of the hosting package completely free of charge.
Availability, price and employee familiarity often determines which operating systems are offered on dedicated servers. Variations of Linux and Unix (open source operating systems) are often included at no charge to the customer. Commercial operating systems include Microsoft Windows Server, provided through a special program called Microsoft SPLA. Red Hat Enterprise is a commercial version of Linux offered to hosting providers on a monthly fee basis. The monthly fee provides OS updates through the Red Hat Network using an application called Yum. Other operating systems are available from the open source community at no charge. These include CentOS, Fedora Core, Debian, and many other Linux distributions or BSD systems FreeBSD, NetBSD, OpenBSD.
Graphical Processing Unit (GPU) cards are used to accelerate analytical solutions, machine learning and deep learning, and engineering/modeling applications. GPUs are used in parallel with CPUs for processing and advanced computation capabilities which allow certain applications to run faster. The following GPUs are available for deployment in your Rackspace dedicated server:

You can take it one step further and add the original email address (the domain one) as a “Send mail as” address under Mail Settings > Accounts and Import. This means that when you reply to an email you received at that address then it goes back from that address. This means that people feel more secure too, as it’s always odd to send an email and have it replied to from a different address – and sometimes somewhat suspicious.
After everyone has an individual account, be sure to create some general accounts for different roles. For example, it’s better to create a [email protected] account than to just have that email go to a specific person (what happens if that person leaves or takes on a new role within the company?). Don’t go overboard though—having too many email accounts can get confusing for everyone.

Things are probably more complicated than that, though. As a recent survey conducted by market research firm Statista clearly shows, email is one of the most popular apps for mobile devices across most organizations and even consumers. Given how many workflows, business processes, and just plain important communications take place over email, this is one area where you likely shouldn't skimp.
I find it really annoying that people who used to check their email regularly, now leave large intervals between accessing their messages. This seems to be a social media thing where they’re all busy putting up their lunch pictures etc. etc. up for ‘everyone’ to see. Unfortunately this behaviour seems to be spilling over to the less conscientious in their work activities and they seem to be treating digital mail with contempt in some cases. Guess it’s back to paper mail and ‘snail’ delivery – not that that always gets the attention it deserves.
Well, depending on your email provider, you can often define several different email addresses that are all delivered into the same mailbox. For example, it’s not at all uncommon for various standard email addresses like “[email protected]”, “[email protected]”, “[email protected]” and so on, to all be delivered into the same mailbox – the mailbox of the administrator for that mail server. I actually go so far as to have many email addresses on my “askleo.com” domain, but only one account. All the email on that domain is delivered to that single account. (I then use rules and filters to sort the email, based on what address it was sent to.)
This is where an email host like SiteGround can be a winning deal for individuals. SiteGround will give you a free domain name, where you get unlimited email hosting that’s compatible with most all major email and webmail clients (RoundCube, Outlook, SquirrelMail, etc.). Your email is secured with integrated anti-SPAM protection, and you can easily manage your account via cPanel, the web’s leading control panel for hosting.
Managed Backup is included with your dedicated server solution. It includes differential daily backups and full weekly backups, with two-week onsite retention. If you require more frequent backups or longer retention periods, we can design a backup solution that meets your business needs. Our backup engineers will work with you to design a backup protocol to reach your recovery time objective (RTO).

Running in-house email servers does provide more control and wider customization as well as tracking and compliance for small to midsize businesses (SMB). But they require specialized on-site IT staff as well as the need to manually manage and support both hardware and software. A third-party hosted email service matches many of the advantages of in-house email without the expensive initial investment. The ability to manage the number of users, access the latest security protocols, and enjoy ease of connectivity and deployment of hosted solutions makes it a viable and competitive option.
For example, in addition to the .in top-level domain, the government of India in 2011[32] got approval for ".bharat", (from Bhārat Gaṇarājya), written in seven different scripts[33][34] for use by Gujrati, Marathi, Bangali, Tamil, Telugu, Punjabi and Urdu speakers. Indian company XgenPlus.com claims to be the world's first EAI mailbox provider,[35] and the Government of Rajasthan now supplies a free email account on domain राजस्थान.भारत for every citizen of the state.[36] A leading media house Rajasthan Patrika launched their IDN domain पत्रिका.भारत with contactable email.

An example here is the rapidly growing trend of "inbox zero." It's actually known by a variety of names, but it refers to the practice of keeping your email inbox count at zero stored emails. Essentially, it's dealing with every email as it comes in and then deleting or archiving each one so that your inbox is always empty. This boils down to a fundamental shift in how users are utilizing their email inboxes.

An email address identifies an email box to which email messages are delivered. A wide variety of formats were used in early email systems, but only a single format is used today, following the specifications[a] developed for Internet mail systems since the 1980s. This article uses the term email address to refer to the addr-spec defined in RFC 5322, not to the address that is commonly used; the difference is that an address may contain a display name, a comment, or both.


Earlier forms of email addresses on other networks than the Internet included other notations, such as that required by X.400, and the UUCP bang path notation, in which the address was given in the form of a sequence of computers through which the message should be relayed. This was widely used for several years, but was superseded by the Internet standards promulgated by the Internet Engineering Task Force (IETF).
Dedicated server hosting gives you full power and total control over your server infrastructure. Built on the latest technology with enterprise-grade hardware, Dedicated Servers give your projects the highest levels of performance. Pick from the latest Intel Xeon processors and choose the resource levels for your project's demands, and with root access you have free choice of Windows and Linux operating systems.
This is how I started doing hosted e-mails, but I recently switched to using Google Apps. If you have a small business (up to 10 users), you can use Google Apps 100% free. Gmail handles the mail, your e-mail has your domain associated with it, and you can link that e-mail up to other Google features (Google docs, Google voice, add-on apps like a CRM or accounting). Best of all, I can sync it all effortlessly with my android phone, so now all of my e-mails still come to my phone… but they’re sorted neatly by account.

The basic EAI concepts involve exchanging mail in UTF-8. Though the original proposal included a downgrading mechanism for legacy systems, this has now been dropped.[31] The local servers are responsible for the local-part of the address, whereas the domain would be restricted by the rules of internationalized domain names, though still transmitted in UTF-8. The mail server is also responsible for any mapping mechanism between the IMA form and any ASCII alias.

It is also necessary to study email alternatives as part of your email service setup plan. Email is the standard way to communicate and it is familiar to most users, but it isn't always the most effective or expedient method. Email can be slow, result in delayed responses, and messages are rarely read to completion. Because of this, many businesses require additional "collaboration" tools, that various email services also include, in order to fill the communication gap more effectively.
The format of email addresses is [email protected] where the local part may be up to 64 octets long and the domain may have a maximum of 255 octets.[4] The formal definitions are in RFC 5322 (sections 3.2.3 and 3.4.1) and RFC 5321—with a more readable form given in the informational RFC 3696[5] and the associated errata. Note that unlike the syntax of RFC 1034,[6] and RFC 1035[7] there is no trailing period in the domain name.

Along with specialized uses for email, you should investigate how your users are emailing on a daily basis. Email has come a long way in 40 years and the way people use it has significantly evolved. That's important because it will impact the tools and features you need to look for in your hosted email provider's client software. Sure, Microsoft Outlook is still the most popular on-site email client, but a fast-increasing number of today's email users are opting for other email clients, such as Thunderbird, or all-web clients, such as Google's hugely popular Gmail. These clients can be very sophisticated and, depending on what your users are doing with email, they can have a big impact on your day-to-day business process.
That's a big difference, with "inbox zero" requiring an email client with great archiving that works over multiple device types. Meanwhile, at the other end of the spectrum, the personal information managers need something more like Microsoft Outlook, with excellent search capabilities as well as a good storage contract on the hosting side because these types of inboxes are often tens of gigabytes (GB) per user.
