Phone Mail Client Setup and Server Settings

You can read your OpenSRS-hosted email right from the Mail app that came with your phone — no extra software to download. This guide walks you through adding your mailbox to the default Mail app on iPhone and the Gmail app on Android, and gives you the server settings to plug in along the way.

How your phone connects to your mailbox

Phone mail apps connect to your OpenSRS mailbox using either IMAP or POP. IMAP keeps your messages and folders in sync across every device you sign in on, so an email you read on your phone shows as read on your laptop too. POP downloads messages to one device and (by default) removes them from the server. If you check email on more than one device, IMAP is almost always the better choice.

Before you begin

• Your full email address (for example, you@yourdomain.com)
• The password for that email address
• The mail server hostname your provider gave you (often mail.yourdomain.com)
• An internet connection on your phone (Wi-Fi or mobile data)

Email server settings

Use these values when your phone asks for incoming and outgoing server details. Replace mail.example.com with the hostname provided by your email provider.

Step 1: Add your mailbox on iPhone (Apple Mail)

1. Open Settings on your iPhone.
2. Scroll down and tap Mail, then tap Accounts.
3. Tap Add Account.
4. Tap Other.
5. Tap Add Mail Account.
6. Enter your name, email address, password, and a description, then tap Next.
7. Choose IMAP or POP at the top, then fill in the incoming and outgoing server settings from the table above. Tap Next.

   Tip: Your iPhone labels the outgoing server fields as optional, but they are required to send mail. Fill them in.

8. Toggle Mail on, then tap Save.

Step 2: Add your mailbox on Android (Gmail app)

1. Open the Gmail app on your phone.
2. Tap your profile picture in the top-right corner.
3. Tap Add another account.
4. Tap Other.
5. Enter your full email address and tap Next.
6. Choose Personal (IMAP) or Personal (POP3).
7. Enter your password and tap Next.
8. Enter the incoming server settings from the table above and tap Next.
9. Enter the outgoing server settings and tap Next.
10. Choose the account options you want (sync frequency, notifications, etc.) and tap Next to finish.

Step 3: Send a test message

1. Open your mail app and compose a new message to yourself.
2. Send it. It should arrive within a minute.
3. Open it to confirm both sending and receiving are working.

Troubleshooting

• "Cannot connect to server." Double-check the hostname, port number, and that SSL is enabled where required.
• Mail receives but won't send. The outgoing (SMTP) settings are usually the culprit. Try port 587 or 465, and make sure authentication is turned on using the same username and password.
• Password rejected. Reset your password in webmail, then update it on your phone.

Next steps

• Set up a desktop email client. See the Email Client Configuration Guide for IMAP, POP, and SMTP settings for Outlook, Thunderbird, Apple Mail, and more.
• Try webmail. If you'd rather skip apps entirely, see The Complete Webmail Guide to use your mailbox from any browser.
• Learn the basics. Once your phone is connected, see How to Use Webmail Mail for tips that apply across devices.
