An email sent from my MacBook using my icloud account bounced back with the error message "Please turn on SMTP Authentication in your mail client". I am using Apple for 10+ years and can't remember running into this problem. Can you help?
Hi TKrabbe,
Thank you for reaching out in Apple Support Communities. There are steps available that can help resolve the inability of sending emails from your MacBook. We recommend for you to follow these steps:
If you can’t send emails in Mail on Mac
In the Mail appon your Mac, if the Send button
is dimmed in the toolbar of your message, or your message can’t be sent using the outgoing Mail server, try these suggestions.
* Make sure the outgoing (SMTP) mail server is specified as directed by the provider of your email account. See Verify an email account’s outgoing server.
* Choose Window > Connection Doctor, then follow the instructions displayed in the Details column.
* If there’s a firewall problem, verify that firewall software isn’t blocking email traffic on port 25, 465, or 587. Also check whether you’re affected by another firewall, such as software installed separately from macOS or built into an internet sharing router, or administered by your email account provider. Contact the appropriate person for information.
Following these steps can help and is outlined in this article: If you can’t send emails in Mail on Mac - Apple Support
Kind regards.
Please turn on SMTP Authentication in your mail client
