Apple iphone outgoing mail rejected by server

Frustrating!

When your iPhone's outgoing mail is rejected by the server, it can be due to various reasons. Here are some common causes and potential solutions:

1. Incorrect email settings: Double-check your email account settings on your iPhone. Make sure the username, password, and server settings are correct.
   • Go to Settings > [your name] > Passwords & Accounts > [your email account] > Account.
   • Verify the settings match the ones provided by your email provider.
2. Server issues: The issue might be on the server side. Try the following:
   • Check your email provider's status page to see if there are any known outages or issues.
   • Try sending an email from a different device or platform to see if the issue is specific to your iPhone.
3. Authentication issues: Ensure that your email account is set up to use the correct authentication method:
   • Go to Settings > [your name] > Passwords & Accounts > [your email account] > Account.
   • Tap "Account" and then "Advanced".
   • Make sure "Use SSL" is enabled and the authentication method is set to "Password" or "OAuth2".
4. Outgoing mail server settings: Verify the outgoing mail server settings:
   • Go to Settings > [your name] > Passwords & Accounts > [your email account] > Account.
   • Tap "Account" and then "Advanced".
   • Check the "SMTP Server" settings, including the server address, port, and authentication method.
5. Firewall or antivirus software: Firewalls or antivirus software might be blocking the outgoing mail connection. Try temporarily disabling them to see if it resolves the issue.
6. iPhone's Mail app settings: Reset the Mail app settings:
   • Go to Settings > [your name] > Passwords & Accounts > [your email account] > Account.
   • Tap "Account" and then "Reset".
   • Confirm that you want to reset the account settings.
7. Email provider's settings: Check with your email provider for any specific settings or requirements for sending emails from an iPhone.
8. Reset network settings: Reset your iPhone's network settings:
   • Go to Settings > General > Reset.
   • Tap "Reset network settings".
   • Confirm that you want to reset the network settings.

If none of these solutions work, you may want to try:

• Restarting your iPhone
• Checking for software updates for your iPhone and email app
• Contacting your email provider's support for further assistance

I hope this helps you resolve the issue with your iPhone's outgoing mail being rejected by the server!
