Smtp Settings For Mac Mail
In the Mail app on 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.
You may be able to send messages from only a certain location, or your email account provider may allow you to send messages but with stricter settings (such as requiring a name and password). Contact your provider, then change the outgoing mail server settings in Mail preferences as needed.
