Edit report at https://bugs.php.net/bug.php?id=73507&edit=1 ID: 73507 Updated by: ab@php.net Reported by: mattcoz at yahoo dot com Summary: Extra space added before additional headers when mail.add_x_header is enabled -Status: Open +Status: Feedback Type: Bug Package: *Mail Related Operating System: Windows PHP Version: 7.0.13 Block user comment: N Private report: N New Comment: I don't reproduce this as well, debugged also through the Windows only sendmail part. @mattcoz at yahoo dot com, there must be something in the configuration, or the data, so we can reproduce this as well. Thanks. Previous Comments: ------------------------------------------------------------------------ [2016-11-13 15:06:23] cmb@php.net I can't reproduce the reported behavior (neither on Windows with php-7.0.13-nts-Win32-VC14-x86, nor on Linux with current PHP-5.6 and PHP-7.0): php -n -d mail.add_x_header=1 -d sendmail_path="cat -" -r "mail('to@email.com', 'Subject', 'Message', 'From: from@email.com');" To: to@email.com Subject: Subject X-PHP-Originating-Script: 1:Command line code From: from@email.com Message ------------------------------------------------------------------------ [2016-11-12 18:10:55] mattcoz at yahoo dot com 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 this bug report at https://bugs.php.net/bug.php?id=73507&edit=1
