Set up your mail client

Want to send and receive your Cyberfusion mail from Thunderbird, Apple Mail on iPhone, Outlook, or another mail app?

This article lists the server settings to enter, and walks through the setup screens for the three most common clients.

Try automatic configuration first

Enter just your email address and password. Most clients configure themselves, as long as the DNS records for mail are set, which by default is the case for domains registered at Cyberfusion.

If the client can't find the settings, enter them by hand:

The username is always your full email address. The full reference is under Server settings.

Step-by-step per client: Thunderbird, iOS Mail, Outlook desktop.

Thunderbird

1. Open the menu (top-right) and select 'Account Settings'.
2. At the bottom of the left sidebar, select 'Account Actions' > 'Add Mail Account'.
3. Enter your name, email address and password. Select 'Continue'.
4. Thunderbird tries to detect the settings. If it succeeds, select 'Done' — you're finished.
5. If detection fails, select 'Configure manually' and enter:
   • Incoming server: IMAP, vmail.cyberfusion.nl, port 993, SSL/TLS, 'Normal password'.
   • Outgoing server: SMTP, vmail.cyberfusion.nl, port 587, STARTTLS, 'Normal password'.
   • Username (both): your full email address.
6. Select 'Done'.

iOS Mail (iPhone, iPad)

1. Open 'Settings' > 'Mail' > 'Accounts' > 'Add Account'.
2. Select 'Other' > 'Add Mail Account'.
3. Enter your name, email address, password and a description. Select 'Next'.
4. At the top, select 'IMAP'.
5. Under 'Incoming Mail Server', enter:
   • 'Host Name': vmail.cyberfusion.nl
   • 'User Name': your full email address
   • 'Password': your mailbox password
6. Under 'Outgoing Mail Server', enter the same three values.
7. Select 'Next'. iOS verifies the settings, which takes a moment.
8. Select 'Save'.

iOS picks port 993 for IMAP and 587 for SMTP on its own.

Verification failed? Open the account you just created, select 'Account' > 'Advanced', and confirm 'Use SSL' is on and the ports match the table above.

Outlook desktop (Windows)

1. Open 'File' > 'Add Account'.
2. Enter your email address. Select 'Advanced options' and tick 'Let me set up my account manually'.
3. Select 'Connect'.
4. Choose 'IMAP' as the account type.
5. Enter:
   • Incoming mail: server vmail.cyberfusion.nl, port 993, encryption 'SSL/TLS'.
   • Outgoing mail: server vmail.cyberfusion.nl, port 587, encryption 'STARTTLS'.
   • Leave 'Require logon using Secure Password Authentication (SPA)' off for both.
6. Select 'Next', enter your mailbox password, and select 'Connect'.

Server settings

Mail server hostname

vmail.cyberfusion.nl

IMAP (recommended)

Keeps your mail on the server, so the same inbox appears on every device.

SMTP (sending mail)

POP3 (only for one device owning the mail)

POP3 downloads mail to a single device and, by default, removes it from the server. Use IMAP unless you have a specific reason not to.
