Setting Up Outlook, Apple Mail and Your Phone for Business Email

You can read Domain India Business Email in Outlook, Apple Mail, Thunderbird or the mail app on your phone, as well as in webmail. This guide gives the exact settings, the steps for each popular app, and the fixes for the mistakes that stop mail from sending.

These settings are for Business Email only. If your mailbox came with a cPanel, DirectAdmin, Webuzo or Plesk hosting plan, it uses different settings: see Business Email vs the email included with your hosting.

1. The settings

Replace yourdomain.com with your own domain. Either sending port works; pick the one your app suggests.

You don't have to type these from this page. Sign in to the client area, open Business Email, open your service and find the Connect your apps card. It shows the incoming and outgoing servers with a copy button for each, and Copy all settings copies the lot.

Two things people get wrong:

• The username is the full address, [email protected], not you.
• The server is your own domain, mail.yourdomain.com. You never type a Domain India hostname into your mail app.

2. IMAP only: there is no POP3

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

POP3 downloads mail to one device and usually deletes it from the server. IMAP keeps your mail on the server and keeps every device in step, so your laptop, your phone and webmail show the same folders, and losing a device doesn't lose your mail.

If your app asks "POP or IMAP?", choose IMAP. If an old guide tells you to use POP3, it was written for a different product.

3. Why automatic setup fails

Most apps try to find your settings automatically when you type your email address. For Business Email this usually fails today, because the automatic-configuration records are not published for customer domains yet. It is a known gap on our side, not a fault in your app.

Choose the manual option instead. Apps call it "Manual setup", "Advanced", "Configure manually" or "Other".

4. Step by step in popular apps

Menu names change between app versions, so use the nearest match if yours looks slightly different.

Outlook

Outlook doesn't always turn on outgoing authentication by itself. Without it, you receive mail but can't send.

Apple Mail, iPhone and iPad

On iPhone or iPad, open Settings, go to the Mail accounts section, tap Add Account, choose Other, then Add Mail Account. On a Mac, open Mail, choose Add Account, then Other Mail Account. Enter your name, full email address and password, choose IMAP if asked, and enter mail.yourdomain.com as both the incoming and the outgoing server. If the device offers to set the account up as POP, decline and choose IMAP.

Android

In your mail app, add an account and choose the manual or "Other" option, then IMAP. In the Gmail app this is Add another account, then Other, then Personal (IMAP). Enter the servers, ports and security from section 1.

Thunderbird

Add a new mail account, enter your name, address and password, then choose Configure manually. Set incoming to IMAP, mail.yourdomain.com, port 993, SSL/TLS; set outgoing to mail.yourdomain.com, port 465, SSL/TLS; and use your full email address as the username for both.

5. Use an app password for each device

Rather than putting your main mailbox password into every device, create an app password for each one: one for your phone, one for Outlook, and so on. Sign in to webmail, open Security, and create one. Each app password is shown once, so paste it into the app straight away.

If a phone is lost or someone leaves, revoke that one app password. Your main password and every other device keep working.

6. Attachment sizes

Business Email accepts messages of up to 100 MB sent through a mail app. Attachments added in webmail are capped lower, at 50 MB per upload.

The recipient's provider has its own limit, and most accept far less than 100 MB. A very large message can leave your mailbox and still be refused by the other side. For big files, send a download link instead.

7. If sending fails but receiving works

Work through these in order:

1. Outgoing authentication is off. Turn on "My outgoing server requires authentication" (or your app's equivalent) with your full address and password.
2. The wrong port is set. Use 465 with SSL/TLS or 587 with STARTTLS. Port 25 is not for sending from a mail app.
3. You hit a sending limit. The server refuses with a temporary 452 error. See Business Email sending limits.
4. The password changed. If the mailbox password was reset, update it in every app, or create an app password.

If receiving fails too, check that you can sign in to webmail. If webmail also refuses your password, it is a password problem, not an app problem. See signing in for the first time.

8. Where Domain India Business Email fits

Business Email works with any standard mail app over IMAP and SMTP with TLS, at your own mail.yourdomain.com hostname. It adds webmail with calendar, contacts and tasks, DKIM signing on every message you send, two-factor authentication and per-device app passwords. It is priced per mailbox, starting from one; the card shows the live price, excluding 18% GST.
