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.
If you have set the DNS records for mail, most clients configure themselves when you enter just your email address and password — try that first. Fall back to the manual settings below only if the client can't find them automatically.
Server settings
Mail server hostname
vmail.cyberfusion.nl
White-label mail
If you have a white-label mail hostname, you can use that everywhere this article shows vmail.cyberfusion.nl. Find the correct one on the platform under 'Mail'.
IMAP — recommended
IMAP keeps your mail on the server, so the same inbox shows up on every device.
| Setting | Value |
|---|---|
| Host | vmail.cyberfusion.nl |
| Port | 993 |
| Encryption | TLS (sometimes shown as SSL/TLS) |
| Username | Your full email address |
| Password | Your mailbox password |
POP3 — only if you specifically want one device to "own" the mail
POP3 downloads mail to a single device and (by default) removes it from the server. Choose POP3 only if you have a specific reason; otherwise use IMAP.
| Setting | Value |
|---|---|
| Host | vmail.cyberfusion.nl |
| Port | 995 |
| Encryption | TLS (sometimes shown as SSL/TLS) |
| Username | Your full email address |
| Password | Your mailbox password |
SMTP — for sending mail
| Setting | Value |
|---|---|
| Host | vmail.cyberfusion.nl |
| Port | 587 |
| Encryption | STARTTLS |
| Username | Your full email address |
| Password | Your mailbox password |
Thunderbird
- Open the menu (top-right) and select 'Account Settings'.
- At the bottom of the left sidebar, select 'Account Actions' > 'Add Mail Account'.
- Enter your name, email address, and password. Select 'Continue'.
- Thunderbird tries to detect the settings automatically. If it succeeds, select 'Done'.
- If detection fails, select 'Configure manually' and enter:
- Incoming server: IMAP,
vmail.cyberfusion.nl, port993, SSL/TLS, 'Normal password'. - Outgoing server: SMTP,
vmail.cyberfusion.nl, port587, STARTTLS, 'Normal password'. - Username (incoming and outgoing): your full email address.
- Incoming server: IMAP,
- Select 'Done'.
iOS Mail (iPhone, iPad)
- Open 'Settings' > 'Mail' > 'Accounts' > 'Add Account'.
- Select 'Other' > 'Add Mail Account'.
- Enter your name, email address, password, and a description. Select 'Next'.
- At the top, select 'IMAP'.
- Under 'Incoming Mail Server', enter:
- 'Host Name':
vmail.cyberfusion.nl - 'User Name': your full email address
- 'Password': your mailbox password
- 'Host Name':
- Under 'Outgoing Mail Server', enter the same three values.
- Select 'Next'. iOS verifies the settings — this takes a moment.
- Select 'Save'.
iOS uses port 993 for IMAP and 587 for SMTP automatically. If verification fails, 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)
- Open 'File' > 'Add Account'.
- Enter your email address. Select 'Advanced options' and tick 'Let me set up my account manually'.
- Select 'Connect'.
- Choose 'IMAP' as the account type.
- Enter:
- Incoming mail: server
vmail.cyberfusion.nl, port993, encryption method 'SSL/TLS'. - Outgoing mail: server
vmail.cyberfusion.nl, port587, encryption method 'STARTTLS'. - Leave 'Require logon using Secure Password Authentication (SPA)' off for both incoming and outgoing.
- Incoming mail: server
- Select 'Next', enter your mailbox password, and select 'Connect'.
Leave SPA off
Cyberfusion mail uses standard password authentication, not Microsoft's 'Secure Password Authentication' (SPA). If you leave SPA on, Outlook can't sign in — even though the password is correct.
