How to Set the Outgoing Mail Server on an iPhone: A Step-by-Step Guide

Setting up an outgoing mail server on an iPhone ensures that you can send emails from your device using your email provider’s server. The process involves a few steps including going into your iPhone’s settings, selecting ‘Mail’, choosing ‘Accounts’, and then adding or editing an SMTP server. Once you’ve adjusted the settings to match those provided by your email provider, your outgoing mail should work seamlessly.

After completing the setup, your iPhone will be able to send emails using the specified outgoing mail server. This means that any emails you compose and send will go through this server, ensuring they reach their intended recipients.


Have you ever had trouble sending emails from your iPhone? Maybe you’ve received an error message or noticed that your emails just aren’t going out? The culprit could very well be your outgoing mail server settings. Setting up the outgoing mail server on your iPhone is crucial for ensuring your emails are sent successfully from your device.

So, why is this important, and who needs to know about it? Well, pretty much anyone with an iPhone and an email account. Whether you’re a busy professional needing to send work emails on the go, a student communicating with professors, or just keeping in touch with friends and family, setting up your outgoing mail server correctly is key to staying connected. Without the proper settings, your emails might not reach their destination, which can be frustrating and potentially problematic. Let’s dive into how to get this set up, so you can send emails with confidence.

Step by Step Tutorial

Before we begin, make sure you have your email provider’s outgoing mail server settings handy. You’ll need them for the setup.

Step 1

Go to ‘Settings’ on your iPhone.

In ‘Settings’, scroll down and tap on ‘Mail’, then select ‘Accounts’.

Step 2

Choose the email account you want to configure or add a new one.

If adding a new email account, select ‘Add Account’ and follow the prompts. If editing an existing account, tap on the account name.

Step 3

Tap on ‘SMTP’ under ‘Outgoing Mail Server’.

You’ll find this at the bottom of the account settings page. SMTP stands for Simple Mail Transfer Protocol, which is the standard for sending emails.

Step 4

Enter your outgoing mail server details.

Use the details provided by your email provider. These typically include the server name, username, password, port number, and whether SSL is required.

Step 5

Save your settings.

Once you’ve entered all the necessary information, tap ‘Done’ in the top right corner to save your settings.

Additional Information

When setting up your outgoing mail server on an iPhone, it’s crucial to know the difference between IMAP and POP. These are two different methods your email service might use to retrieve emails. IMAP syncs emails with the server, so if you read an email on your iPhone, it shows as read on your desktop too. POP, on the other hand, downloads emails to your device, and actions you take won’t reflect on the server or other devices. This is why it’s vital to get the right settings from your email provider.

Another tip is to ensure that your iPhone’s software is up to date. Occasionally, updates include changes that can affect email settings and functionality. Keeping your device updated can prevent potential problems.

Remember to test your outgoing mail server setup by sending an email to yourself or a friend. If it doesn’t work, double-check your settings or contact your email provider for assistance. Setting up the outgoing mail server on an iPhone can be tricky, but once it’s done, it makes email communication smooth and reliable.


  1. Access ‘Settings’ and tap ‘Mail’, then ‘Accounts’.
  2. Select the email account to configure or add a new one.
  3. Go to ‘SMTP’ under ‘Outgoing Mail Server’.
  4. Enter the required server details as provided by your email provider.
  5. Save the settings by tapping ‘Done’.
