What need users to put in the whitelist of their mailbox to prevent WP generated mails to end up in spam?

Say the server use something like that:

wp_mail( '[email protected]', 'The subject', 'The message', 'From: My Name <[email protected]>' );

Is it working if users just put '[email protected]' in the whitelist? Or what should they use?

Honestly, this also has nothing to do with WordPress. It is more web server whitelisting issue. You should start with this link.

SPF records are important.

And maybe your web server has IP address that is blacklisted. You may even consider different IP address from your provider.
