Dear all, We are developing some imap/php programme. Right now, we would like to add some additional header field in the email. The question is 1. Are there standard (spare) fields for us to add? 2. How do we read them? We have found mail_elt function in imap but don't know if it can fetch all the header fields and how can we parse it... Many thanks!!!
