I'm having to use SMTP as my host has just stopped support for the php mail command but there's one issue I'm encountering. When I receive an email or the recipient receives an automated reply email then the "from" field is getting filled in with the email address I have set up in the "WP Mail SMTP" settings.
I have tried entering the correct email address in the "Custom E-mail From (optional):" field as well as checking the "Enable when web host requires "Mail From" strictly tied to domain email account." checkbox on the form settings but it's still coming back with the email address from WP Mail SMTP and not the one I would like.
The actual from name is working just not the email.
Any help would be greatly appreciated.
