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:

1. Log in to cPanel

2. Click Email Accounts

3. Select your email address

4. Click Check Email or Connect Devices

You will see:

• Outgoing Server (SMTP): mail.yourdomain.com

• SMTP Port: 587 (TLS) or 465 (SSL)

• Authentication: Required

• Username: Full email address

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:

1. Log in to Roundcube Webmail

You can confirm exact values from cPanel if needed.

Horde webmail often hides SMTP details but still allows access.

Steps:

2. Click Settings

3. Open Mail Server or Personal Information

4. 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:

1. Log in to your hosting control panel

2. Navigate to Email Settings

3. Open Mail Configuration or SMTP Settings

4. Copy the outgoing server details

Common formats:

If webmail doesn’t clearly show SMTP details, many providers follow standard patterns.
