• How to Enable SMTP Authentication on iOS (iPhone/iPad)

    This guide provides step-by-step instructions on how to configure your outgoing mail server (SMTP) settings on your iOS device (iPhone or iPad) to ensure that you are using authenticated sending. This is often necessary when you are experiencing issues sending email, especially when connected to a different network than your email provider's (e.g., using a home Wi-Fi network with a work email account).
    Note: The exact menu names may vary slightly depending on your specific iOS version, but the general navigation path remains consistent.

    Prerequisites

    Before you begin, ensure you have the following information from your email service provider:
    •Outgoing Mail Server (SMTP) Hostname: (e.g., smtp.example.com)
    •SMTP Port: (Commonly 587 for secure TLS/STARTTLS, or 465 for SSL)
    •Authentication Type: (Usually Password)
    •Username: (Often your full email address)
    •Password: (Your email account password)

    Step-by-Step Guide

    Follow these steps to access and configure your SMTP settings:

    1. Navigate to Mail Account Settings

    1.Open the Settings app on your iPhone or iPad.
    2.Scroll down and tap Mail.
    3.Tap Accounts.
    4.Select the email account you wish to modify.

    2. Access the Outgoing Mail Server (SMTP) Settings

    1.On the Account screen, tap on your Account (usually listed as your email address).
    2.Under the Outgoing Mail Server section, tap SMTP.
    3.Tap on the Primary Server (it will typically be the hostname of your outgoing server, for example mydomain.ie).

    3. Configure Authentication

    This is the crucial step where you enable and verify the authentication settings.
    1.Ensure the Server toggle is set to ON.
    2.Verify the Host Name and User Name are correct. The User Name is typically your full email address.
    3.Enter your Password in the dedicated field.
    4.Check the Use SSL setting. It should generally be ON for secure connections.
    5.Verify the Server Port is correct (e.g., 587 or 465).
    6.Tap Authentication and select Password. This explicitly tells iOS to use your provided username and password to log in to the SMTP server before sending mail.

    4. Save and Test

    1.Tap Done or < Account in the top-left corner to save your changes. iOS will attempt to verify the new settings.
    2.If the settings are correct, you will be returned to the previous screen.
    3.Open the Mail app and send a test email to yourself or a colleague to confirm that the outgoing mail server is now working correctly with SMTP authentication enabled.

    Troubleshooting

    Issue
    Potential Solution
    "Cannot Send Mail" Error
    Double-check the Password and User Name for typos. These are the most common points of failure.
    Settings Revert/Fail to Save
    Try deleting and re-adding the email account entirely, as this forces iOS to re-establish all server connections.
    Mail is Sent, but is Marked as Spam
    This is usually a server-side issue, but ensure your Host Name is correct and that you are using the recommended Port and SSL settings.
    Authentication option is missing
    Ensure the Server toggle is ON. If the server is off, the authentication options may be hidden.
