To find the SMTP server in webmail, you usually need to log in to your webmail account, open the email or server settings section, and look for “Outgoing Mail Server” or “SMTP Settings,” where the server address, port number, and encryption type are listed. Most webmail services clearly display these details so you can configure email clients, websites, or applications to send emails using that account.
Introduction
SMTP (Simple Mail Transfer Protocol) is essential for sending emails from any email service, website, or application. Whether you’re setting up an email client like Outlook or Thunderbird, configuring WordPress SMTP, or connecting a CRM or mobile app, you’ll need the correct SMTP server details. Webmail interfaces—such as cPanel Webmail, Roundcube, Horde, or custom webmail dashboards—are the most reliable place to find this information.
This guide explains what an SMTP server is, why you need it, and step-by-step methods to find SMTP server details in webmail, even if you’re not technical.
What Is an SMTP Server?
An SMTP server is the outgoing mail server responsible for sending emails from your account to other email servers. While IMAP or POP3 handles incoming emails, SMTP ensures emails are delivered securely and correctly.
Typical SMTP Details Include:
SMTP server address (example: mail.yourdomain.com)
Port number (usually 587 or 465)
Encryption type (TLS or SSL)
Authentication requirement
Username and password
Why You Need SMTP Details from Webmail
Finding SMTP settings in webmail is important when:
Email is not sending from your website
You want to use an email client instead of webmail
You are setting up WordPress or a contact form
You need secure email delivery (TLS/SSL)
You want better inbox placement and fewer spam issues
Webmail provides official and accurate SMTP settings for your email account, reducing configuration errors.
How to Find the SMTP Server in Webmail? Best Guide
Method 1: Find SMTP Server in cPanel Webmail (Most Common)
If your hosting uses cPanel, this is the easiest method.
Step-by-Step:
Log in to cPanel
Click Email Accounts
Select your email address
Click Check Email or Connect Devices
Scroll to Mail Client Manual Settings
You will see:
Outgoing Server (SMTP): mail.yourdomain.com
SMTP Port: 587 (TLS) or 465 (SSL)
Authentication: Required
Username: Full email address
Password: Email password
This information works for websites, apps, and email clients.
Method 2: Find SMTP Server in Roundcube Webmail
Roundcube is a popular webmail client used by many hosting providers.
Steps:
Log in to Roundcube Webmail
Click Settings
Go to Server Settings or About
Look for SMTP Server or Outgoing Mail
If SMTP details are not shown directly, Roundcube usually uses:
SMTP server:
mail.yourdomain.comPort:
587Encryption:
STARTTLS
You can confirm exact values from cPanel if needed.
Method 3: Find SMTP Server in Horde Webmail
Horde webmail often hides SMTP details but still allows access.
Steps:
Log in to Horde Webmail
Click Settings
Open Mail Server or Personal Information
Look for Outgoing Server details
If not visible, check your hosting provider’s email setup documentation or cPanel email settings.
Method 4: Find SMTP Server in Custom Webmail or Hosting Dashboard
Some hosting companies use custom dashboards instead of cPanel.
General Steps:
Log in to your hosting control panel
Navigate to Email Settings
Open Mail Configuration or SMTP Settings
Copy the outgoing server details
Common formats:
smtp.yourdomain.com
mail.yourdomain.com
Port 587 (recommended)
Method 5: Check SMTP Settings from Email Provider Defaults
If webmail doesn’t clearly show SMTP details, many providers follow standard patterns.
Common SMTP Server Formats:
Shared hosting: mail.yourdomain.com
Business email: smtp.yourdomain.com
Google Workspace: smtp.gmail.com
Microsoft 365: smtp.office365.com
Ports:
587 (TLS – recommended)
465 (SSL – legacy but still supported)
How to Verify the SMTP Server Is Correct
After finding SMTP details in webmail, test them.
Quick Test Options:
Configure an email client (Outlook/Thunderbird)
Send a test email from the WordPress SMTP plugin
Use an SMTP testing tool
If the test email sends successfully, your SMTP server is working.
Common SMTP Errors and Fixes
SMTP Authentication Failed
Ensure username is the full email address
Confirm the password is correct
Authentication must be enabled
Connection Timed Out
Use port 587 instead of 25
Check firewall restrictions
Confirm encryption type
Emails Not Sending but No Error
Enable SMTP authentication
Verify SSL/TLS settings
Confirm server hostname
SMTP Security Best Practices
Always use TLS or SSL encryption
Never use port 25 unless required
Keep email passwords secure
Avoid sharing SMTP credentials
Use domain-based authentication (SPF, DKIM, DMARC)
These practices improve security and email deliverability.
