note 116940 added to function.mail

When setting additional headers while sending email, do not add an entry for "Subject" as shown in some examples. Yahoo mail (and likely a few others) will not accept any emails with a "Subject" declared in the additional headers along with "Reply to", "From", etc. It took two years and a lot of headache to finally discover this tidbit via trial and error. ---- Server IP: 72.52.91.14 Probable Submitter: 64.134.240.77 ---- Manual Page -- http://php.net/manual/en/function.mail.php Edit -- https://master.php.net/note/edit/116940 Del: integrated -- https://master.php.net/note/delete/116940/integrated Del: useless -- https://master.php.net/note/delete/116940/useless Del: bad code -- https://master.php.net/note/delete/116940/bad+code Del: spam -- https://master.php.net/note/delete/116940/spam Del: non-english -- https://master.php.net/note/delete/116940/non-english Del: in docs -- https://master.php.net/note/delete/116940/in+docs Del: other reasons-- https://master.php.net/note/delete/116940 Reject -- https://master.php.net/note/reject/116940 Search -- https://master.php.net/manage/user-notes.php
