note 94446 added to function.mail

I really don't think this is a bug in code or a bug in PHP itself, but I've just spent about 4 hours debugging the mail() function on my Qmail server, only to finally go into the command line and run the mail() command and find that Qmail reports an injection error in the headers section of the mail() function. It looks like this: ===== [root@mail ~]# php -r "mail('email@domain.com, email2@domain.com', 'CLI Test', 'This is a CLI Test', 'From: me@domain.com\r\nReply-To: return@domain.com\r\nX-Mailer: PHP/'.phpversion().'\r\n');" qmail-inject: fatal: unable to parse this line: From: me@domain.com\r\nReply-To: return@domain.com\r\nX-Mailer: PHP/5.1.6\r\n [root@mail ~]# ===== Therefore, for other people's sanity, make sure that you use double-quotes, not single-quotes (a.k.a. ticks) when setting up email headers on a Qmail server. Make the change to the header section as stated and it works: ===== [root@mail ~]# php -r "mail('me@domain.com, you@domain.com', 'CLI Test', 'This is a CLI Test', \"From: me@domain.com\r\nReply-To: return@domain.com\r\nX-Mailer: PHP/\".phpversion().\"\r\n\");" [root@mail ~]# ===== Here's the actual PHP code. This code works: <?php $headers = "From: $fromName <$fromEmail>" . "\r\n" . "Reply-To: $fromName <$fromEmail>" . "\r\n" . "Return-Path: return@domain.com" . "\r\n" . "Content-Type: text/plain; charset=ISO-8859-1; format=flowed; boundary=\"$mime_boundary\"" . "\r\n" . "MIME-Version: 1.0" . "\r\n" . "X-Mailer: PHP/" . phpversion() . "\r\n" . "Organization: Your Organization"; mail($to, $subject, $body, $headers); ?> Where this code does not: <?php $headers = 'From: $fromName <$fromEmail>' . '\r\n' . 'Reply-To: $fromName <$fromEmail>' . '\r\n' . 'Return-Path: return@domain.com' . '\r\n' . 'Content-Type: text/plain; charset=ISO-8859-1; format=flowed; boundary=\'$mime_boundary\'' . '\r\n' . 'MIME-Version: 1.0' . '\r\n' . 'X-Mailer: PHP/' . phpversion() . '\r\n' . 'Organization: Your Organization'; mail($to, $subject, $body, $headers); ?> The only change is the single versus double quotes. Once I switched it to double-quotes, all emails are received. This was difficult to debug because Sendmail and PHP were returning 'FALSE' on the mail() function due to the Qmail injection failure that I mentioned above and the mail() function doesn't seem to have much debugging assitance. Hopefully that save someone else 4 hours that it cost me. :( ---- Server IP: 208.69.120.35 Probable Submitter: 64.140.176.30 ---- Manual Page -- http://www.php.net/manual/en/function.mail.php Edit -- https://master.php.net/note/edit/94446 Del: integrated -- https://master.php.net/note/delete/94446/integrated Del: useless -- https://master.php.net/note/delete/94446/useless Del: bad code -- https://master.php.net/note/delete/94446/bad+code Del: spam -- https://master.php.net/note/delete/94446/spam Del: non-english -- https://master.php.net/note/delete/94446/non-english Del: in docs -- https://master.php.net/note/delete/94446/in+docs Del: other reasons-- https://master.php.net/note/delete/94446 Reject -- https://master.php.net/note/reject/94446 Search -- https://master.php.net/manage/user-notes.php
