 > In this case, the email will be tagged as spam because the from header
 domain doesn't the top-level domain.
 This is not correct. Subdomains carry the same reputation as the parent
 domain.

 The fact that the email is ending in the spam box is completely unrelated
 to the use of a subdomain. The important thing here is how your MTA is
 configured, not which subdomain is being used in WP. Probably you have
 configured your MTA with your domain and this is why your emails are not
 fully compliant spam-wise
 ([https://www.cs.columbia.edu/~hgs/research/projects/spam-from/ being the
 `From` is different to the `Received` hostname])

 Using the subdomain for the email, when the site is using a subdomain, is
 just a matter of consistency and what a user should expect by default.

 Be aware, that many users could be using a subdomain without access to the
 domain for several reasons beyond their control. The fact that you just
 happen to have access to both domain and subdomain is simply your specific
 use case but does not generalize well.

 If you personally find that the subdomain is not doing any good for the
 reasons stated above, you can always edit it manually. For example, you
 can directly hook to `wp_mail_from` filter and return the email you want
 to use for those `From`.

 Closing this as `wontfix`
