Bug #73507 [NEW]: Extra space added before additional headers when mail.add_x_header is enabled

From: mattcoz at yahoo dot com Operating system: Windows PHP version: 7.0.13 Package: *Mail Related Bug Type: Bug Bug description:Extra space added before additional headers when mail.add_x_header is enabled Description: ------------ When the server is set up with the mail.add_x_header preference enabled, an extra space is added before the additional headers. In my example where I set the From address in my additional headers, this causes it to add an additional From header. The email is then blocked if sent to gmail addresses. This does not happen on another server running PHP 5.3.13 with the same settings. I've attempted to look at the mail.c code and find the problem, but I don't see anywhere that might explain why the extra space is being added. Test script: --------------- mail("to@email.com", "Subject", "Message", "From: from@email.com"); Expected result: ---------------- To: <to@email.com> X-PHP-Originating-Script: 0:test.php From: <from@email.com> Actual result: -------------- To: <to@email.com> X-PHP-Originating-Script: 0:test.php From: from@email.com From: <from@email.com> -- Edit bug report at https://bugs.php.net/bug.php?id=73507&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73507&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73507&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73507&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73507&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73507&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73507&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73507&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73507&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73507&r=support Expected behavior: https://bugs.php.net/fix.php?id=73507&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73507&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73507&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73507&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73507&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73507&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73507&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73507&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73507&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73507&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73507&r=mysqlcfg
