Last updated on Mar 06, 2026

You can access your Redcloud mailbox from a desktop computer using Mozilla Thunderbird, a free and open-source email client available for Windows, Linux, and macOS.

This guide explains how to configure Thunderbird to connect to your Redcloud email account.

What you need

Before starting, make sure you have:

• Your Redcloud email address
• Your email password

Mail server settings

Use the following settings when configuring your email client.

Incoming mail (IMAP)

Server: mail.redcloud.be
Port: 993
Security: SSL/TLS
Authentication: Normal password
Username: your full email address

Outgoing mail (SMTP)

Server: mail.redcloud.be
Port: 587
Security: STARTTLS
Authentication: Normal password
Username: your full email address

Step 1. Install Thunderbird

Download Thunderbird from the official website:

https://www.thunderbird.net

Install the application and start Thunderbird.

Step 2. Add your Redcloud email account

  1. Open Thunderbird

  2. Click Email under Set up an account

  3. Enter:

Name
Your name

Email address
Your Redcloud email address

Password
Your mailbox password

  1. Click Continue

Thunderbird will try to detect the server automatically.

Step 3. Configure the server settings

If Thunderbird does not configure the account automatically:

  1. Click Configure manually

  2. Enter the following settings.

Incoming server

Thunderbird will now connect to the Redcloud mail server and start synchronizing your mailbox.

Step 4. Verify your folders

After setup you should see your mailbox folders:

• Inbox
• Sent
• Drafts
• Junk
• Trash

Send a test email to verify that sending and receiving works.

Troubleshooting

Cannot connect to server

Verify:
