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 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

  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 automatically. If it succeeds, select 'Done'.
  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 (incoming and outgoing): 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 — this takes a moment.
  8. 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)

  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 method 'SSL/TLS'.
    • Outgoing mail: server vmail.cyberfusion.nl, port 587, encryption method 'STARTTLS'.
    • Leave 'Require logon using Secure Password Authentication (SPA)' off for both incoming and outgoing.
  6. 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.
