When I send e.g. a sales invoice, the e-mail is sent by email@example.com and when the customer replies to the e-mail, it is shown in the Communications List, but it isn’t linked to the Sales Invoice document.
I assume this is because the reply-to address in the e-mail sent by ERPNext is also firstname.lastname@example.org. When the customer sends an email to the address that includes the Sales Invoice number (e.g. sales+Sales%20Invoice+ACC-SINVemail@example.com), the received email gets correctly linked to the Sales Invoice.
Is there a setting such that the reply-to address includes the document number so replies by the customer automatically get linked to the correct document?
