setting a bounce header with UE
I set up a contact form using UE4 which should trigger an email message to the client. The email messages are not arriving at the client's email box. To troubleshoot whether the form is working, I cc'd myself and the messages arrive correctly. I can email to the clients mailbox with no problem, so I know that their account is functioning.
I'm wondering if there's an error message being generated for the main message (to the client's email), so I'd like to specify a bounce-back header. Does UE have a way to do this?
I set the contact form to use a from address from the form (the person filling out the form specifies their email). That way the client could hit reply. Is there a problem with that, for example might it trigger the client's spam filter if the email is coming from the website's server and not the visitor's email server? Maybe that could cause the message to fail to hit their inbox?
I'd appreciate any more ideas on how to troubleshoot this issue.
