I am getting "Rejected by the server because it does not allow relaying" error on my iPhone
The error is present when the Outgoing SMTP server email settings (hostname, username, and password) aren’t properly configured on your device.
If you are a SiteGround customer, find your email settings in Site Tools > Email > Accounts > go to the kebab menu > Mail Configuration.
Next, access your iPhone and navigate to:
- Settings > Mail.
- Go to Account > Outgoing Mail Server and select SMTP.
- Select your Primary Server.
- Fill the Outgoing server Host name, your email address (e.g. john@yourdomain.com) as Username and place the email password accordingly.
- Tap Done to save your changes.
Note: In case you don’t know your email password you can change it from your Site Tools > Email > Accounts > go to the kebab menu > Change Password.
