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

Setting the outgoing mail server on an iPhone is a simple process that involves navigating to the Settings app, selecting Mail, choosing the email account you want to adjust, and then entering the specific server information provided by your email service provider. Once set up, your iPhone will be able to send emails using the specified server.

After completing this action, your iPhone will send all outgoing emails through the server you have just set up. This can help ensure that your emails are sent securely and reliably.


Email has become an essential part of our daily lives, and for many of us, our iPhone is the primary device we use for managing our email accounts. Whether for personal or professional use, being able to send emails from your iPhone is crucial. But what happens when you can’t send an email? Often, the issue lies with the outgoing mail server settings.

The outgoing mail server, also known as SMTP (Simple Mail Transfer Protocol) server, is responsible for the delivery of emails you send out. If these settings are not correctly configured, your emails won’t go anywhere. That’s why it’s important to know how to set the outgoing mail server on your iPhone. This process is especially relevant for those who use email services that require manual setup, or if you’re having trouble sending emails from your iPhone.

Setting the outgoing mail server correctly ensures that your emails are sent promptly and reach their intended recipients without any hitches. So, whether you’re setting up a new email account on your iPhone or troubleshooting email issues, let’s dive into how to get this done.

Step by Step Tutorial: Setting the Outgoing Mail Server on an iPhone

Before we begin, ensure you have the outgoing server settings provided by your email service provider. These typically include the server name, username, password, port number, and SSL requirement.

Step 1: Open Settings

Open the Settings app on your iPhone.

This is the app with the gear icon that is usually found on your home screen.

Step 2: Tap on Mail

Scroll down and tap on ‘Mail’.

This will take you to the Mail settings where you can manage accounts and preferences related to email.

Step 3: Select Accounts

Tap on ‘Accounts’.

This will show you a list of all the email accounts that are set up on your iPhone.

Step 4: Choose the Email Account

Select the email account you wish to configure.

If you have multiple accounts, make sure to choose the one that needs the outgoing server settings adjusted.

Step 5: Tap on Account

Tap on ‘Account’ once more.

This will take you to the settings specific to the selected email account.

Step 6: Tap on SMTP

Scroll down and tap on ‘SMTP’ under the Outgoing Mail Server section.

This is where you will enter the server settings that control how your emails are sent out.

Step 7: Select the Primary Server

Tap on the primary server. It will usually be labeled with your email provider’s name and ‘SMTP’.

This is the server your iPhone currently uses to send emails.

Step 8: Enter Server Settings

Fill in the required server settings information.

Make sure to enter the exact details provided by your email service provider.

Step 9: Save Changes

Once you’ve entered all the information, tap ‘Done’ to save the changes.

It’s crucial to hit ‘Done’ or your settings will not be saved, and you may continue to experience issues with sending emails.


Secure Email SendingOnce you set the outgoing mail server with the correct settings, your emails are sent through a secure channel, reducing the risk of interception or tampering.
Reliable DeliveryProperly setting your outgoing mail server ensures your emails reliably reach their destination without being lost or bouncing back.
Control Over SendingWith the right server settings, you have more control and flexibility over the sending process, such as the option to use different servers for different email accounts.


Complexity for BeginnersFor those not familiar with email server settings, the process can seem complex and daunting at first.
Potential for ErrorsIncorrectly entering server settings can lead to emails not being sent, which can be frustrating and time-consuming to troubleshoot.
Dependence on Email ProviderYou are dependent on the email service provider’s server settings, which may change, requiring you to update the settings on your iPhone.

Additional Information

When setting up your outgoing mail server, it’s essential to know whether your email service provider requires authentication for the server. This usually means that you need to input the same username and password that you use to check your email. Additionally, be aware of the security protocol your provider recommends. SSL (Secure Sockets Layer) is commonly used for encrypting the connection to the mail server, ensuring that your emails are sent securely.

Another tip is to ensure that your iPhone’s software is up to date. Sometimes, issues with sending emails can be resolved by simply updating to the latest iOS version, as it comes with bug fixes and improvements. Also, consider whether you need to use an alternate port number based on your provider’s recommendations or if you are on a network that blocks the default port.

Remember, setting the outgoing mail server is just one part of the email setup. Make sure your incoming mail server settings are also correctly configured. If you ever change your email password, you’ll need to update the password in your outgoing server settings as well, or else you won’t be able to send emails.
