Have you ever found yourself unable to work efficiently because an unexpected error message from the outgoing server prevented you from sending an urgent email? We know how frustrating it is when, whilst setting up your email client, you have to navigate a maze of unfamiliar ports, encryption protocols and complicated abbreviations. Most users are rightly concerned that a single incorrect setting could result in the loss of their previous emails, or that their account might not be adequately protected against external threats. Without a precise understanding of the technical parameters, configuring email can often seem like an unnecessary waste of time and a risk.
This guide will show you exactly how to set up your email on any device using the most secure protocols. Our aim is to ensure your email remains perfectly synchronised across all platforms, whilst sending emails is fast and error-free thanks to SSL/TLS protocols. You’ll learn about the technical differences between IMAP, POP3 and SMTP; we’ll help you configure the ports correctly; and we’ll also introduce cPanel solutions supported by NVMe servers, built on aWh’s 10 years of experience. This knowledge will help ensure that your email system remains stable, secure and reliable in the long term.
What is an email client and why is it worth using?
An email client is an application that you can install directly on your workstation or smartphone to manage your digital correspondence more efficiently. Many people ask: What is an email client, and how does it differ from webmail accessed via a browser? Whilst webmail is an interface running on a remote server, the client utilises local resources, thus providing faster search capabilities and offline access to previous messages. When setting up an email client, you are not merely configuring a piece of software, but building a bridge between your own device and the remote mail server.
In 2026, efficiency will be the most important factor in the workplace. With a dedicated program, you can manage multiple accounts simultaneously on a single interface, whether for business or personal email. Setting up the email client allows you to connect to aWh’s high-performance NVMe servers and synchronise your messages, calendar and contacts at lightning speed. Whilst webmail interfaces are convenient, they are often slower and more limited in terms of functionality. With a client program, however, you can read or write emails even when you don’t have an internet connection. As soon as you’re back online, the system automatically synchronises the changes. This process runs particularly smoothly on aWh’s modern infrastructure, as the ‘Connect Devices’ function in the cPanel interface almost entirely automates the transfer of the necessary settings.
Popular email clients in 2026
There is a wide range to choose from, but most users opt for one of three main options. Microsoft Outlook remains a mainstay in the corporate sector, as it offers deep integration with calendar management and teamwork. Mozilla Thunderbird is ideal for those who value freedom and customisability, particularly amongst fans of open-source solutions. On mobile devices, the Gmail app and the devices’ native email clients dominate. Whilst configuration for these programs is now often fully automated, knowing how to set them up manually is essential for troubleshooting.
The basics of a professional appearance
In the business world, credibility is determined by first impressions. Using your own domain, rather than an address from a free service provider, conveys professionalism and stability. Centralised corporate email not only enhances security but also aids brand building with every message sent. If you too would like to build trust with your customers and avoid the pitfalls of spam filters, registering a domain for a credible email address is the first step towards a successful online presence. aWh’s 10 years of experience guarantees that your email system will function flawlessly from a technical point of view.
IMAP or POP3? Choosing the right protocol
When configuring email, the first and most important technical decision is which retrieval protocol to use. Setting up an email client is not just about entering server details, but also about how we want to manage our data on a day-to-day basis. IMAP or POP3? This question fundamentally determines the user experience and the accessibility of data. Whilst one focuses on continuous synchronisation across multiple devices, the other focuses on local data storage and freeing up storage space.
The essence of IMAP (Internet Message Access Protocol) is its cloud-based operation. In this case, emails remain on the server, whilst the client program merely displays a mirror image of them. This will be essential by 2026, as most of us use smartphones, laptops and office computers simultaneously. If we read or delete a message on one device, it is immediately updated on all other devices. The aWh team of experts primarily recommends using IMAP, as this guarantees consistency in the folder structure and sent emails across all platforms.
The benefits of IMAP in the modern workplace
As well as real-time synchronisation, IMAP’s greatest advantage is secure centralised storage. If you lose your phone or your laptop breaks down, your emails won’t be lost, as they are stored on aWh’s secure, NVMe-based servers. Using the automated tools available on the cPanel interface, setting up an IMAP-based email client can be done in a matter of seconds, avoiding synchronisation errors caused by manual data entry.
When might POP3 still be justified?
POP3 (Post Office Protocol) is an older protocol, but one that is still useful in certain situations. It works by downloading emails from the server to your local device and then, by default, deleting them from the remote server. This can be advantageous if, due to strict internal policies, you only wish to store messages on your own machine, or if the available email storage capacity is limited. Using POP3 prevents your inbox from becoming full, but in return you have to forego the convenience of synchronisation across multiple devices.
Once you have selected the appropriate protocol, the next step is to enter the server details accurately and enable encryption. If you are looking for a stable and fast platform for your business correspondence, choose from our professional email hosting plans, where technical support and security are always guaranteed.
Manual setup of an email client: Step by step
Knowing how to set up a manual email client is essential if you are using bespoke software that does not support automatic detection, or if your network environment requires a specific configuration. The first and most important step is to obtain information from a reliable source. For aWh customers, the most accurate source of information is the cPanel interface, where, under the ‘Email Accounts’ menu item, clicking the ‘Connect Devices’ button provides immediate access to all the necessary parameters. This interface also includes server names, ports and the required encryption methods.
For the incoming mail server (Incoming Server), you must choose between the IMAP and POP3 protocols. In a modern working environment, we almost always recommend using IMAP due to its multi-device synchronisation capabilities. A critical step during configuration is to enable encryption. Under the 2026 security requirements, the use of unencrypted channels is no longer permitted, as data and passwords would be easily intercepted. The outgoing server always uses the SMTP protocol. Here, you must ensure that the ‘Outgoing server requires authentication’ option is enabled and that it uses the same login details as the incoming server.
General configuration details (aWh standard)
For most email clients, you can use the following standard settings to ensure smooth operation:
- Username: Your full email address (for example: info@sajatdomained.hu).
- Password: The unique password for this email account.
- Incoming server: mail.yourdomain.hu (or the name of your hosting server).
- Incoming ports: 993 (SSL/TLS) for IMAP, 995 (SSL/TLS) for POP3.
- Outgoing server: mail.yourdomain.hu (or the name of your hosting server).
- Outgoing port: 465 (SSL/TLS).
Automatic configuration using cPanel
Whilst knowing the manual settings is useful for troubleshooting, the automation available on aWh hosting accounts significantly simplifies the process. Pre-configured profiles can be downloaded via the cPanel interface, allowing email client setup to take place automatically without any manual intervention. This is particularly advantageous on iOS devices (iPhone and iPad) and in the desktop versions of Outlook. The system then automatically creates the account, sets the correct ports and activates the secure SSL connection. If you get stuck during the process, you’ll find detailed technical guides on how to use this feature on the ‘Help with cPanel’ page.
For us, security isn’t an option – it’s a fundamental requirement. All our NVMe-based hosting plans support the latest encryption standards, ensuring your emails remain protected from unauthorised access. When configuring settings manually, always ensure that the SSL/TLS options are enabled, as using old, unencrypted ports (such as 110 or 143) can now pose a serious risk to the security of your business data.
Common errors and solutions during setup
Even with the most accurate details to hand, it can happen that setting up your email client doesn’t work first time. A significant proportion of errors stem from minor oversights, which are easily rectified. The most common issue is an authentication error. It is important to note that the username is always the full email address, not just the part before the @ symbol. When entering passwords, be mindful of upper and lower case letters, and check that Caps Lock is not enabled. A common mistake is accidentally including a space when copying a password, which results in an invalid login. If the program repeatedly rejects your login, it is worth typing the password in manually rather than using the clipboard.
Failure to send outgoing emails is usually due to a lack of SMTP authentication. Many email clients leave this feature disabled by default. If you are receiving emails but cannot send them, check your outgoing server settings. The ‘Outgoing server (SMTP) requires authentication’ tick box must be ticked. In addition, timeout errors often indicate local network issues or firewall restrictions. The email filtering functions of antivirus programs sometimes block secure ports, so it is worth temporarily disabling these whilst testing.
Security restrictions and how to lift them
aWh’s servers employ high-level protection against unauthorised access. GeoIP protection, for example, can restrict access from certain overseas regions. If you are abroad and cannot connect, you can check or amend these security rules via the cPanel interface. Another common occurrence is the temporary blocking of an IP address. If a device on your network attempts to log in with an incorrect password too many times, the system will block that IP address for security reasons. In this case, please wait 15–30 minutes or contact our support team for assistance. It is also crucial to check SSL certificates, as an expired or incorrectly installed certificate will trigger an immediate security warning in the client, preventing the encrypted connection from being established.
Modern security challenges
In the technological landscape of 2026, the use of two-factor authentication (2FA) and the OAuth2 protocol has become standard practice. When setting up your email client, if 2FA is enabled on your account, you cannot use your traditional password directly within the client program. Instead, you will need a unique, application-specific password generated via the cPanel interface. The latest versions of Outlook already support modern authentication, where you must authorise the login in a pop-up browser window. If you are using older software that does not support the OAuth2 standard, the connection will fail unless you configure the security exceptions correctly.

Frequently Asked Questions
What is the difference between a hostname and an email address?
The hostname is the server’s technical address (for example, mail.yourdomain.hu), whilst the email address is your unique identifier within the system. When setting up your email client, the hostname determines which physical server the software should connect to in order to retrieve data. You must enter your email address as your username for authentication. It is important that the hostname matches exactly the details provided by your hosting provider; otherwise, the connection will not be established.
Which port should I use for SMTP: 465 or 587?
On aWh’s infrastructure, we primarily recommend using port 465 with SSL/TLS encryption to ensure maximum security. Whilst port 587 uses the STARTTLS protocol, port 465 provides an encrypted channel right from the start of the connection. This setting ensures that outgoing emails leave the device in an encrypted state, protecting business secrets from unauthorised interception. Always check that the correct encryption method is selected for the port in the client.
Why am I getting a ‘Security Warning’ message in the client?
The security warning usually appears when the configured server name does not match the name on the SSL certificate. For example, if you are using the address mail.mydomain.hu but the certificate is issued for the server’s hostname, the client will flag the connection as suspicious. This error can be avoided by entering the exact server name shown in the cPanel interface. Less commonly, the warning may also be caused by the certificate having expired or by interference from a local antivirus program.
How do I set up my email on an iPhone or Android?
On mobile devices, the simplest method is to use cPanel’s ‘Connect Devices’ feature, which carries out the configuration automatically. For the manual process, go to the settings menu, select the option to add a new account, then enter the IMAP details. When setting up your email client, the process can be completed by downloading a configuration profile on an iPhone, or by manually entering the server details on an Android device. Ensure that the SSL/TLS options are enabled alongside ports 993 and 465.
Why can I receive emails but not send them?
If receiving emails works but sending fails, this almost always indicates a lack of SMTP authentication or incorrect settings. With most email clients, you need to specifically select the option for the outgoing server to use the same login details as the incoming server. It is also possible that your internet service provider is blocking the standard ports, or that your local firewall is blocking the traffic. In such cases, it is worth trying to change the port or check the authentication method.
Do you need a separate password for SMTP and IMAP?
Normally, you should use the same password for the incoming and outgoing servers as the one you provided when setting up your email account. The exception to this is modern systems where two-factor authentication (2FA) is in place. In such cases, you will need a unique application password generated via the cPanel interface, which is specific to that particular client program. This solution enhances security, as the main password does not need to be stored directly within various applications or on mobile devices.
What should I do if I’ve forgotten my email account password?
If you have forgotten your login details, you cannot retrieve your password; you can only set a new one via the hosting control panel. Log in to the aWh cPanel, navigate to the ‘Email Accounts’ menu item, then select the management option next to the address you wish to change. Here, you can immediately set a new, secure password, which will allow synchronisation to resume. Don’t forget to update the new password on all your devices where you have previously used that account.
How can I export my emails to another client?
The simplest method is to use the IMAP protocol, which automatically synchronises your emails with the new program as soon as you log in. However, if you wish to transfer an offline archive, the solution is to export to a PST file in Outlook, or to the MBOX format in Thunderbird. Once the data has been imported, the folder structure and messages will appear unchanged in the new environment. Always make a backup before starting the process to avoid data loss.
