Business Email Setup on Ruk-Com Cloud 2026 — @yourdomain.com
Guide to setting up business email on Ruk-Com Cloud for beginners and general users

Why businesses should use a professional email
A professional email address matching your domain name such as [email protected] signals immediate credibility and organisational seriousness to customers, partners, investors, and potential clients in ways that generic free email addresses simply cannot replicate. Research across B2B purchasing contexts consistently shows that decision-makers are significantly more likely to engage with and respond to email communications from domain-matched addresses, perceiving them as more legitimate and trustworthy than messages originating from consumer email services. Ruk-Com Cloud includes email hosting capabilities with most of its hosting plans, enabling you to create and manage professional email accounts on your own domain without any additional monthly subscription cost, making the transition from personal to professional email financially accessible for businesses of all sizes. Beyond the credibility benefits, corporate email hosting on your own domain provides meaningful brand protection by enabling proper email authentication configuration through SPF, DKIM, and DMARC records that make it significantly harder for malicious actors to impersonate your organisation in phishing attacks targeting your customers or business partners.
- Builds trust with customers and partners
- Cleanly separates personal and business communications
- Memorable and professional, e.g. [email protected]
- Create multiple accounts per department, e.g. sales@, support@
- Full control over your communications, independent of Gmail
How to configure MX records for email on Ruk-Com Cloud
From our hands-on testing — an MX record, short for Mail Exchange record, is the DNS record type that tells the global email infrastructure which mail server is responsible for accepting incoming email messages addressed to your domain. Without a correctly configured MX record, email sent to addresses at your domain has no routing information and will be bounced back to senders as undeliverable, making MX records absolutely essential for any domain that needs to receive email. Configuring MX records on Ruk-Com Cloud is done through the DNS Manager section of the control panel by adding an MX record entry that points to your mail server hostname, which is typically in the format mail.yourdomain.com or a specific hostname provided by Ruk-Com Cloud in your account setup documentation. The Priority value in an MX record determines the preference order when multiple mail servers are configured — lower numeric values indicate higher preference, so a server with priority 10 is contacted before one with priority 20. For basic single-server configurations, setting a priority of 10 is standard practice. After adding or modifying MX records, allow the DNS changes to propagate fully before testing email delivery, which typically takes between one and four hours for most global DNS resolvers to reflect the update.
- MX record specifies the receiving mail server with a priority
- Lower priority number means primary server (10 < 20 < 30)
- Configure in the DNS Manager on Ruk-Com Cloud
- After changing MX, wait for DNS propagation (30 min to 24 hours)
- Test with an MX lookup tool such as MXToolbox
SMTP, IMAP and POP3 settings for Ruk-Com Cloud email
Configuring an email client application such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail to work with your Ruk-Com Cloud email account requires entering the correct incoming and outgoing mail server settings that correspond to your hosting configuration. For the incoming mail server using the IMAP protocol, which is strongly recommended for most users due to its server-synchronisation architecture, use mail.yourdomain.com as the hostname with port 993 and SSL/TLS encryption enabled. If you prefer POP3, which downloads messages to a single device rather than synchronising across multiple devices, use the same hostname with port 995 and SSL/TLS encryption. For the outgoing mail server handling email sending via SMTP, use mail.yourdomain.com with either port 465 for direct SSL/TLS or port 587 with STARTTLS upgrade, both providing equivalent security. Your authentication username is your complete email address including the domain portion, and the password is the one you set when creating the account in the Ruk-Com Cloud control panel. IMAP is strongly preferred over POP3 for anyone accessing email from more than one device, as it keeps all messages and folders synchronised on the server so that reading, deleting, or organising email on one device is immediately reflected everywhere else you access that account.
- SMTP is for sending email — typically port 587 (STARTTLS)
- IMAP is for receiving email synced across devices — port 993 (SSL)
- POP3 downloads email to local storage — port 995 (SSL)
- Username is the full email address (including @domain.com)
- Always enable encryption (TLS/SSL) when configuring
SPF record setup to prevent email spoofing
SPF, which stands for Sender Policy Framework, is a DNS TXT record that publishes a list of IP addresses and server hostnames that are authorised to send email messages on behalf of your domain. When a recipient mail server receives a message claiming to originate from your domain, it performs a DNS lookup for your SPF record and checks whether the sending server's IP address is included in the authorised list. If the sending IP fails the SPF check, the receiving server may mark the message as spam, quarantine it, or reject it entirely depending on how strictly the recipient's mail server enforces SPF policy. Configuring SPF on Ruk-Com Cloud involves adding a TXT record in the DNS Manager that specifies the authorised sending sources for your domain. A basic SPF record for a domain whose email is sent exclusively through Ruk-Com Cloud mail servers takes the form of a TXT record containing the policy string specifying the relevant include directive for Ruk-Com Cloud's mail infrastructure. The tilde-all qualifier at the end, written as approximately tilde followed by all, implements a soft fail policy that marks non-authorised sources as suspicious rather than outright rejecting them, which is appropriate during initial testing before tightening to a hard fail policy once you have confirmed all legitimate sending sources are correctly listed.
- Add SPF as a TXT record in DNS Manager
- Example: v=spf1 include:mail.ruk-com.cloud ~all
- ~all means softfail (recommended), -all means hardfail
Setting up DKIM to improve email credibility
DKIM, which stands for DomainKeys Identified Mail, is an email authentication mechanism that adds a cryptographic digital signature to every outgoing email message, enabling recipient mail servers to verify that the message genuinely originated from an authorised server for your domain and that the message content was not altered or tampered with during transmission across the internet. DKIM operates using asymmetric public-private key cryptography: your mail server uses a private key kept securely on the server to sign each outgoing message by computing a cryptographic hash of specified message headers and body content, and the corresponding public key is published in DNS as a TXT record so that any receiving mail server can retrieve it and verify the signature without needing the private key. Configuring DKIM on Ruk-Com Cloud is typically handled through the control panel's email or DNS section, where the system generates the key pair automatically and provides the exact TXT record string you need to add to your domain's DNS configuration. After adding the DNS record and waiting for propagation, you can verify that DKIM is working correctly by sending a test message to a verification service or examining the email headers in received messages for the DKIM-Signature field. SPF, DKIM, and DMARC should always be configured together as they form complementary layers of email authentication that collectively provide much stronger protection against spoofing than any single standard alone.
- Get the DKIM key from Ruk-Com Cloud email settings
- Add the DKIM key as a TXT record in DNS Manager
- DKIM record is typically at selector._domainkey.yourdomain.com
How to stop business emails landing in the spam folder
Email messages landing in recipients' spam folders instead of their inbox is a common and commercially damaging problem for businesses using corporate email, as important communications including quotes, order confirmations, and client correspondence may be missed or significantly delayed. The root causes of poor email deliverability typically fall into several categories that can be diagnosed and addressed systematically. Absent or incorrectly configured email authentication records are the most common cause — if your domain is missing SPF, DKIM, or DMARC records, or if these records contain errors, receiving mail servers have no way to verify your messages are legitimate and default to treating them as suspicious. The IP address of your mail server appearing on one or more real-time blacklists is another common cause, often resulting from previous misuse of shared hosting infrastructure. Email content characteristics that resemble spam patterns — such as excessive use of certain keywords, high image-to-text ratios, missing plain text versions, or broken HTML formatting — can also trigger spam filters even when authentication is correctly configured. Use MXToolbox.com to check your sending IP against major blacklists, verify your authentication records with email header analysis tools, and build sending reputation gradually by starting with lower volumes and ensuring early recipients actively mark your messages as legitimate.
- Verify SPF, DKIM and DMARC are all correctly configured
- Check if the server IP is on any blacklist at mxtoolbox.com/blacklists
- Request delisting if the IP is blacklisted without cause
Configuring business email on Outlook, Thunderbird and mobile
From multiple reviews, setting up your Ruk-Com Cloud corporate email in Microsoft Outlook involves opening the application, navigating to File and then Account Settings, clicking Add Account, and entering your email address. When prompted, choose the option to configure server settings manually rather than relying on automatic detection, which may not correctly identify Ruk-Com Cloud's server configuration. Enter the incoming mail server as mail.yourdomain.com with IMAP protocol on port 993 with SSL/TLS encryption, and the outgoing SMTP server as mail.yourdomain.com on port 465 with SSL/TLS or port 587 with STARTTLS — your full email address as the username and your email account password for authentication. In Mozilla Thunderbird, go to Account Settings and click Add Mail Account, enter your name, email address, and password, then let Thunderbird attempt automatic configuration. If automatic detection fails to find the correct settings, click Configure Manually and enter the IMAP and SMTP server details described above. On iOS devices, go to Settings, then Mail, then Accounts, tap Add Account, select Other, and choose Add Mail Account — entering the same server details. Android users should open their email application's settings, choose to add a new account, select Manual Setup when prompted, choose IMAP as the account type, and enter the Ruk-Com Cloud server settings to complete the configuration.
- Outlook: File > Add Account > enter email and server settings
- Thunderbird: Tools > Account Settings > Add Account
- iOS/Android: Settings > Mail > Add Account > Other
- Use IMAP not POP3 for multi-device sync
