Setting Up Outlook, Apple Mail and Your Phone

These are the settings for Business Email. If your mailbox is the one bundled with a cPanel, DirectAdmin, Plesk or Webuzo hosting plan, these settings will not work — use the guide for your control panel instead.

Settings

Incoming (IMAP)
  Server:     mail.yourdomain.com
  Port:       993
  Security:   SSL/TLS
  Username:   your full email address
  Password:   your mailbox password

Outgoing (SMTP)
  Server:     mail.yourdomain.com
  Port:       465  with SSL/TLS          (recommended)
     or       587  with STARTTLS
  Username:   your full email address
  Password:   your mailbox password
  Authentication: required

Two things people get wrong:

• The username is the full address, [email protected], not you.
• The server is your own domain, mail.yourdomain.com — not a vendor hostname.

There is no POP3

Business Email does not offer POP3, and the ports are closed. This is deliberate.

POP3 downloads mail to one device and, in its usual configuration, removes it from the server. IMAP keeps your mail on the server and synchronises it, so the same mailbox looks the same on your laptop, your phone and webmail — and your mail survives losing the device.

If a mail client offers you "POP" and "IMAP", choose IMAP. If you are following an old guide that says POP3, that guide is for a different product.

Automatic setup

Mail clients that offer to "find settings automatically" will currently fail for Business Email, because the autoconfiguration DNS records are not yet published. This is a known gap on our side, not a fault in your client.

Enter the settings manually using the table above. Choose the manual, advanced or "configure manually" option when your client offers to do it for you.

Outlook

Use Manual setup or additional server types → IMAP. Let Outlook finish, then check under More Settings → Outgoing Server that "My outgoing server (SMTP) requires authentication" is ticked. Outlook does not always set this, and without it your mail will be received but never sent.

Apple Mail, iPhone and iPad

Add the account as Other → Add Mail Account, then enter the IMAP and SMTP details above. iOS will sometimes offer to set the account up as POP — decline and choose IMAP.

Android

Use your mail app's manual setup and choose IMAP. Gmail's app calls this "Other" or "Personal (IMAP)".

App passwords, and why you should use one

Rather than putting your main password into every device, generate a per-device app password from your webmail settings — one for your phone, one for Outlook, and so on.

If a device is lost or an employee leaves, revoke that one credential. Your password and every other device stay untouched.

Attachment sizes

You can send messages of up to 100 MB through a mail client. Uploads through webmail are capped slightly lower, at 50 MB.

Bear in mind that the recipient's provider has its own limit, and most are far smaller — Gmail accepts 25 MB and Microsoft 365 around 20 MB. A 90 MB message will leave us happily and then be rejected by the recipient. For genuinely large files, send a link.

If sending fails but receiving works

Almost always one of:

1. SMTP authentication is not enabled in the client.
2. The client is using port 25 for sending. Use 465 or 587.
3. You have hit a sending limit — see the sending limits article.
