Useful information about email settings
- To prevent spam, most Internet providers block/redirect port 25. To circumvent this, we've enabled email submission on TCP port 587.
- When configuring the outgoing mailserver, ensure to activate the SMTP Authentication-option.
- Mobile customers with a laptop and most home users should use port 587 for outgoing mail (SMTP).
- If you are unable to change the SMTP port, use the SMTP server of your local Internet service provider.
When using one of the secured services such as SMTPS / IMAPS / POP3S, ensure that SSL authentication (password-based) is selected. The username/password combination that is needed for authentication is the full email address and password for that Inbox. When adding your email account to your client, or when using Webmail, please ensure to enter the full address when logging in.
POP3 versus IMAP
POP3 is the well-known way to retrieve emails from a mail server over TCP/IP connection. By default, most email clients using POP3 collect mail from your inbox and download it to the computer. This prevents your Inbox from filling up. The downside is that it is not very flexible, a message downloaded to one computer is no longer in the Inbox, therefore it cannot be viewed from another computer any more.
IMAP gained popularity as it addresses this shortfall of POP3. The mail is viewed from the Inbox (but it can still be downloaded for caching or backup purposes), and it can be marked as read/unread and categorized in folders. All modern and mobile email clients support IMAP. IMAP is also the protocol used by most Webmail front-ends to communicate with the mail server. The downside is that it is your responsibility to prevent your Inbox from overflowing. When an Inbox is full, new messages will be rejected.
