We are using the latest version of WordPress and WP Mail SMTP.
The test email sends without an issue.
Sending an email via wp_mail with no headers works without issue.
However, as soon as I add headers to wp_mail the email fails to send.
My headers are as follows:
From: Some Dude <some@email.com> \r\n Reply-To: some@email.com \r\n
Please advise.
