Written by Blog

Quick Answer: To access your webmail, navigate to https://yourdomain.com/webmail (or https://yourdomain.com:2096) and log in with your full email address and password. To connect your custom email to Outlook, iPhone, or Android, use Secure IMAP Settings: Incoming Server: mail.yourdomain.com (Port 993 with SSL/TLS), Outgoing Server: mail.yourdomain.com (Port 465 with SSL/TLS).

Direct Webmail Access URLs

You can access your email from any browser anywhere in the world without installing software:

  • https://yourdomain.com/webmail
  • https://yourdomain.com:2096 (Direct Secure Port)
  • https://webmail.yourdomain.com

Universal Secure Mail Configuration Settings

Protocol Server Hostname Port Security / Encryption Authentication
Incoming (IMAP) mail.yourdomain.com 993 SSL / TLS Full Email & Password
Incoming (POP3) mail.yourdomain.com 995 SSL / TLS Full Email & Password
Outgoing (SMTP) mail.yourdomain.com 465 (or 587) SSL / TLS Requires Authentication

Connecting Custom Domain Email to iPhone (iOS Mail)

  1. Open Settings > Mail > Accounts > Add Account.
  2. Select Other > Add Mail Account.
  3. Enter your Name, Email, Password, and Description.
  4. Select IMAP at the top. Under Incoming Mail Server, enter Host Name mail.yourdomain.com and full User Name.
  5. Under Outgoing Mail Server, enter Host Name mail.yourdomain.com, full User Name, and Password.
  6. Tap Save. iOS will automatically verify SSL certificates and sync your mailboxes.

Connecting Custom Domain Email to Microsoft Outlook

  1. In Outlook, click File > Add Account.
  2. Enter your full business email address, check Let me set up my account manually, and click Connect.
  3. Select IMAP.
  4. Enter Incoming Port 993 (Encryption: SSL/TLS) and Outgoing Port 465 (Encryption: SSL/TLS).
  5. Enter your password and click Done.

Troubleshooting Outlook and iPhone SSL Certificate Mismatches

When connecting an email client, if Outlook or Apple Mail displays a warning stating “The server you are connected to is using a security certificate that cannot be verified”, the client is connecting to mail.yourdomain.com while the SSL certificate covers the shared hosting server hostname. To resolve this:

  1. In cPanel, open SSL/TLS Status and ensure AutoSSL has issued a valid Let’s Encrypt certificate covering mail.yourdomain.com.
  2. Alternatively, configure your incoming and outgoing server hostnames to the primary server hostname (e.g. server12.cpanelfree.com) to leverage the server’s master wildcard SSL certificate.

Managing IMAP Folder Subscriptions in Apple Mail

If sent messages or trash folders do not synchronize on iPhone, navigate to Settings > Mail > Accounts > [Your Account] > Advanced > Mailbox Behaviors and map Sent Mailbox to the server’s Sent folder.

Frequently Asked Questions

Should I choose IMAP or POP3 for my mobile phone?

Always choose IMAP. IMAP synchronizes folders, read states, and sent messages in real time across all devices, while POP3 downloads messages locally to a single device.

Configuring Microsoft Outlook 365 Autodiscover Records

To enable instant 1-click email setup in desktop Outlook without manually typing server hostnames or port numbers, create an Autodiscover CNAME Record in your domain DNS zone:

Type: CNAME
Host: autodiscover
Value: autodiscover.yourdomain.com (or server hostname)

Pro Sysadmin Tip: Resolving Apple Mail IMAP Namespace Issues

If custom folders created in Roundcube do not appear in Apple Mail, go to Settings > Mail > Accounts > Advanced and set IMAP Path Prefix to INBOX.

With secure IMAP and SMTP configurations in place, you can manage your custom business correspondence across all your mobile and desktop devices with seamless real-time synchronization.

Troubleshooting Outlook Send/Receive Synchronization Delays

If Microsoft Outlook displays delays when fetching incoming messages, navigate to Send / Receive Groups > Define Send/Receive Groups and reduce the automated synchronization schedule from 30 minutes to 2 minutes. This forces real-time IMAP polling across all active folders.

Can I configure my custom business email on both iPhone and Outlook simultaneously?

Yes. Because IMAP synchronizes email state directly on the cloud server, any message read, archived, or deleted on your iPhone will immediately reflect in Microsoft Outlook and Roundcube webmail.

Following these standard server port and encryption settings ensures that your email clients remain responsive, secure, and fully synchronized across all mobile and desktop devices.
