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.

the way universal email works is to create the email message, hand it over to the SMTP server, from there, the SMTP server relays the message to the recipient.

The SMTP server will not make any sort of response back with the results, you would need to look into the SMTP servers error logs to see why it is not relaying the message. You would need to contact the host for this info.


It is possible that it is a problem with the from address. Some SMTP servers require the from address to be a valid email address on the smtp servers domain. If this is the cxase, you can set the from address to a hard coded value, then set the reply to address to use the form input.
