Check for headers in the email where we embed the enquiry id. If present it will match on this. Emails sent from TProfile embed this automatically.
If this header information is not present (when the customer has emailed the inbound email address directly or their email client has stripped these headers out) we look for an enquiry where there is an associated contact with the email address the inbound email was sent from. It will only match if it finds a single enquiry, this avoids incorrect information going to the wrong enquiry/agentthen filters enquiries with a departure date in the future and takes the closest enquiry to date/time the inbound email was received.
