#20340 [NEW]: mail() incorrectly strips multiple \r\n

From: _@mrmachine.net Operating system: Windows XP SP1 PHP version: 4CVS-2002-11-10 PHP Bug Type: Mail related Bug description: mail() incorrectly strips multiple \r\n tested on 4.3pre2 and 4.3-snapshot (2002-11-10). php4/win32/sendmail.c contains: /* This pattern removes \r\n from the start of the string, * \r\n from the end of the string and also makes sure every line * is only wrapped with a single \r\n (thus reduces multiple * occurences of \r\n between lines to a single \r\n) */ #define PHP_WIN32_MAIL_RMVDBL_PATTERN "/^\r\n|(\r\n)+$/m" #define PHP_WIN32_MAIL_RMVDBL_REPLACE "" i'm not certain if the applicable specification(s) require that there be NO multiple occurences of \r\n in a mime message, but this addition has broken compatibility with outlook express clients at the very least, which seems to depend on multiple \r\n to separate content blocks. it will also unecessarily alter valid mail content, and therefore i believe \r\n should only be stripped from the beginning and end of the message, if at all. example code: --cut-- $headers = 'From: _@mrmachine.net' . "\r\n"; $headers .= 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-Type: multipart/mixed;' . "\r\n"; $headers .= ' boundary="703c1875a9605c5619dd34f7642dcad8"' . "\r\n"; $headers .= 'Content-Transfer-Encoding: 7bit' . "\r\n\r\n"; $headers .= 'This is a multi-part message in MIME format.' . "\r\n\r\n"; $headers .= '--703c1875a9605c5619dd34f7642dcad8' . "\r\n"; $headers .= 'Content-Type: text/html;' . "\r\n"; $headers .= ' charset="iso-8859-1"' . "\r\n"; $headers .= 'Content-Transfer-Encoding: 7bit' . "\r\n\r\n"; $headers .= '<pre>' . "\r\n"; $headers .= 'test paragraph 1' . "\r\n\r\n"; $headers .= 'test paragraph 2' . "\r\n"; $headers .= '</pre>' . "\r\n\r\n"; $headers .= '--703c1875a9605c5619dd34f7642dcad8--' . "\r\n"; mail('_@mrmachine.net', 'test', null, $headers); --cut-- the above code will deliver a seemingly empty email. if the message source is viewed, you will find that even had the content been displayed, it would not be as the sender had intended (no blank line between paragraphs): --cut-- Content-Transfer-Encoding: 7bit <pre> test paragraph 1 test paragraph 2 </pre> --703c1875a9605c5619dd34f7642dcad8-- --cut-- -- Edit bug report at http://bugs.php.net/?id=20340&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20340&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20340&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20340&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20340&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20340&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20340&r=support Expected behavior: http://bugs.php.net/fix.php?id=20340&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20340&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20340&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20340&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20340&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20340&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20340&r=isapi
