Email hosting is a specialist internet hosting service which operates email servers. Hosting your email with one.com means you can benefit from premium services such as an ad-free interface, email on your own domain, spam and virus protection as well as black and white lists. Your email, calendar and contacts are also accessible via webmail in any browser, so your work can travel with you.

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.


A domain-based email is a personalised or custom mailbox with a unique address – usually on your own domain name, e.g. [email protected] Create an email address using your registered domain name to have a professional mailbox that is connected to your brand. It not only builds your brand reputation but also instils customers and prospects with the confidence that you’re a legitimate business.
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 This was widely used for several years, but was superseded by the Internet standards promulgated by the Internet Engineering Task Force (IETF).
Before registering a domain, it is necessary to choose your desired name. That is the most crucial step. Once you have done so, you can use the domain check at the top of this page to help you find out, if your website address is available or if it is already in use. In case all your preferred names are already under management, you can choose a completely new one or try another extension.

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]
One great way to protect data is by using email encryption. This feature can do wonders for protecting your organization's privacy and that of your employees, but it demands some investigation when you're selecting your provider. Is it built-in or do you require a third-party tool? Does it use common standards that the recipient can process? What about Secure Sockets Layer (SSL) certificates? Are they included or do they need to be purchased separately? The best-in-class tools will not only make encryption easy for anybody to configure and use, buy they'll also make it easy for you to understand pre-purchase.
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.
Line speed, billed on the 95th percentile, refers to the speed in which data flows from the server or device, measured every 5 minutes for the month, and dropping the top 5% of measurements that are highest, and basing the usage for the month on the next-highest measurement. This is similar to a median measurement, which can be thought of as a 50th percentile measurement (with 50% of measurements above, and 50% of measurements below), whereas this sets the cutoff at 95th percentile, with 5% of measurements above the value, and 95% of measurements below the value. This is also known as Burstable billing. Line speed is measured in bits per second (or kilobits per second, megabits per second or gigabits per second).
Providers often bill for dedicated servers on a fixed monthly price to include specific software packages. Over the years, software vendors realized the significant market opportunity to bundle their software with dedicated servers. They have since started introducing pricing models that allow dedicated hosting providers the ability to purchase and resell software based on reduced monthly fees.

Interpretation of the local part of an email address is dependent on the conventions and policies implemented in the mail server. For example, case sensitivity may distinguish mailboxes differing only in capitalization of characters of the local-part, although this is not very common.[13] Apart from work, school, or organization addresses, gmail ignores all dots in the local-part for the purposes of determining account identity.[14] This prevents the creation of user accounts your.user.name or yourusername when the account your.username already exists.
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.
At IONOS, we always strive to offer our products at competitive price levels - for all customers. However, due to the sheer size of our product portfolio, we cannot guarantee to have the best price available for all products, all the time. Instead, we focus on a selected range of domain extensions which are frequently sought after by our customers, such as a .com, and provide those domain names to you using a very aggressive price point.
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.
RAID stands for redundant array of independent disks. It’s a technology that distributes data across multiple storage devices to provide improved reliability. RAID 1 is a commonly implemented RAID level that mirrors data across two separate storage drives to ensure redundancy – so if one disk fails, the data remains available. Software RAID uses the host operating system to manage the RAID process, while hardware RAID uses its own dedicated hardware.
In practice, the form validation of some web sites may reject special characters such as "+" in an email address – treating them, incorrectly, as invalid characters. This can lead to an incorrect user receiving an e-mail if the "+" is silently stripped by a website without any warning or error messages. For example, an email intended for the user-entered email address [email protected] could be incorrectly sent to [email protected] In other cases a poor user experience can occur if some parts of a site, such as a user registration page, allow the "+" character whilst other parts, such as a page for unsubscribing from a site's mailing list, do not.
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?
