An email address such as [email protected] is made up of a local-part, an @ symbol, then a case-insensitive domain. Although the standard requires[1] the local part to be case-sensitive, it also urges that receiving hosts deliver messages in a case-independent fashion,[2] e.g., that the mail system at example.com treat John.Smith as equivalent to john.smith; some mail systems even treat them as equivalent to johnsmith.[3] Mail systems often limit their users' choice of name to a subset of the technically valid characters, and in some cases also limit which addresses it is possible to send mail to.
Microsoft offers software licenses through a program called the Service Provider License Agreement. The SPLA model provides use of Microsoft products through a monthly user or processor based fee. SPLA software includes the Windows Operating System, Microsoft SQL Server, Microsoft Exchange Server, Microsoft SharePoint and shoutcast hosting, and many other server based products.
Your next major concern will be compatibility. It's not a shock that most businesses run on Microsoft Windows and use some form of Microsoft Office. Being able to use common third-party clients such as Microsoft Outlook can often be a concern, and even today, compatibility with Microsoft Outlook isn't necessarily guaranteed. This is especially true when sending and receiving meeting invites. It only takes one garbled meeting invite to realize how frustrating this can be in the real world. Even if using Microsoft Outlook isn't a concern, portability is. If the service is entirely web-based, then is there a means for me to take my email offline and send email when I connect?
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.)
The local-part postmaster is treated specially—it is case-insensitive, and should be forwarded to the domain email administrator. Technically all other local-parts are case-sensitive, therefore [email protected] and [email protected] specify different mailboxes; however, many organizations treat uppercase and lowercase letters as equivalent. Indeed, RFC 5321 warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where ... the Local-part is case-sensitive".

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.
Many dedicated server providers include a service level agreement based on network up-time. Some dedicated server hosting providers offer a 100% up-time guarantee on their network. By securing multiple vendors for connectivity and using redundant hardware, providers are able to guarantee higher up-times; usually between 99-100% up-time if they are a higher quality provider. One aspect of higher quality providers is they are most likely to be multi-homed across multiple quality up-link providers, which in turn, provides significant redundancy in the event one goes down in addition to potentially improved routes to destinations.
Ultimately, it boils down to a balance between cost, features, and risk. It's always tempting to simply jump on the lowest-cost solution, but the fact that email is ubiquitous keeps this from being the smart play. It's nearly impossible to escape using it, which means your users, your customers, and the guts of your business have all come to depend on it in different ways. You need to discover those ways, evaluate them, and then choose a service that either meets or improves on them. This takes time, discussion with your IT staff, and some investigation; these are steps you don't want to skip. Otherwise, you'll pay for it later.
That has interesting implications: it means you can control what email gets downloaded when by having more than one account. I could separate askleo.com into two accounts, for example: one for the email addresses I want to pay attention to quickly, and the other for things that aren’t as critical. You could also segregate email based on which address it was sent to, which is what I do with my askleo.com email.
The transmission of electronic mail within the Internet uses the Simple Mail Transfer Protocol (SMTP), defined in RFC 5321 and 5322, and extensions like RFC 6531. The mailboxes may be accessed and managed by users with the Post Office Protocol (POP) or the Internet Message Access Protocol (IMAP) with email client software that runs on a personal computer, mobile device, or with webmail systems that render the messages on a screen or on paper printouts.
Note that some mail servers wildcard local parts, typically the characters following a plus and less often the characters following a minus, so [email protected] and [email protected] might end up in the same inbox as [email protected] or even as [email protected] This can be useful for tagging emails for sorting, see below, and for spam control.[10] Braces { and } are also used in that fashion, although less often.[citation needed]
Many services allow hundreds for forwarding rules or aliases to be created. Suppose John runs a small business but wants to give website visitors the confidence that they’re dealing with a solid company. He could create forwarding rules for [email protected], [email protected], [email protected], and so on, and have them all forwarded to [email protected] As John adds employees he can change the forwarding rules to go to other email addresses—you can have as many aliases as you want pointing to the same destination email.

A dedicated server, or computing server, is a server where all the physical resources of the machine are available. Unlike a virtual server, which uses a portion of the resources to run its virtualisation technology, a dedicated server allows you to benefit from all of the machine’s available RAM, storage, and computing power. With cloud computing, we can also define this type of solution as "bare metal", highlighting the physical availability of the machine’s resources, in contrast to standard solutions based on virtual instances.
If you want to be safe, go with something like [email protected], [email protected], [email protected], or [email protected] Sure, there will always be exceptions to the rule (if two people have the exact same name, maybe you can force them into a Hunger Games-type situation), but doing what you can to avoid future duplication will make your life much easier later.
Dedicated hosting services primarily differ from managed hosting services in that managed hosting services usually offer more support and other services. As such, managed hosting is targeted towards clients with less technical knowledge, whereas dedicated hosting services, or unmanaged hosting services, are suitable for web development and system administrator professionals.
The addresses found in the header fields of an email message are not directly used by mail exchanges to deliver the message. An email message also contains a message envelope that contains the information for mail routing. While envelope and header addresses may be equal, forged email addresses are often seen in spam, phishing, and many other Internet-based scams. This has led to several initiatives which aim to make such forgeries easier to spot.

It’s pretty much common knowledge that Gmail is awesome. It’s fast, connects seamlessly with the rest of your Google services such as Drive, has a cool app called Inbox, and is overall an extremely powerful email service. However, to use it with a custom domain, you need to purchase Google Apps for either $5 or $10/month, which for casual users is a bit unnecessary. On top of that, you don’t even get all of the features a personal account gets, e.g. Inbox.


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.
Once you get your custom email address set up, your next task is to create individual email addresses (the part before the @). Fortunately (or unfortunately, if you’re bad at making decisions), the possibilities are endless. You can use your first name, your last name, some combination of the two, generic words like “owner” or “support”, nicknames like “bossman” or “lordofemail”, or any other name you can think of.
