Bug #73485 [Com]: mail() adds a lone CR or LF

Edit report at https://bugs.php.net/bug.php?id=73485&edit=1 ID: 73485 Comment by: sherwoodsports at gmail dot com Reported by: sherwoodsports at gmail dot com Summary: mail() adds a lone CR or LF Status: Feedback Type: Bug Package: Mail related Operating System: All PHP Version: 7.0.X Assigned To: yohgaki Block user comment: N Private report: N New Comment: Unfortunately, I'm in a Windows Server 2008 R2 environment. After reading it, that script indicates right away that it won't run on Windows. I use the IIS web server to swap PHP versions that IIS is using for any given web site. The SMTP server is Microsoft CDO (basically Microsoft Exchange Libraries) and it has never changed (this library is no longer updated via Microsoft) between various server web languages (ASP, PHP 5.3.24) and has only experienced issues with PHP 7 and above. All that said, it would be difficult to say a library that has never changed is suddenly sensitive to PHP 7 (I still have PHP 5 installed and it still doesn't fail). Do you have a script that will run on Windows? Is there a command that fails on Windows that I can modify in that script such that it will run successfully? Previous Comments: ------------------------------------------------------------------------ [2016-12-12 07:13:04] yohgaki@php.net Are you sure that you are using the same MTA (mail server) and UMA (sendmail binary) for old and new PHPs? If not, MTA/UMA behavior change is the cause most likely. If you are using the same MTA/UMA, please modify following test script and reproduce issue. https://github.com/php/php-src/blob/master/ext/standard/tests/mail/mail_basic.phpt ------------------------------------------------------------------------ [2016-11-25 15:21:43] sherwoodsports at gmail dot com Thank you for re-opening. A manipulated MTA/UMA likely would not explain why the older version of PHP works, but the newer version does not. Also, all CRLF's used in the code are using PHP_EOL and are not using manual ('\n\r') characters to end lines. No single \r or \n characters are used, therefore are not subject to the non-conversion issue you suggest. This also supports the fact that the older PHP versions prior to 7 works without issues, but 7 does have issues. ------------------------------------------------------------------------ [2016-11-25 07:05:22] yohgaki@php.net I reopened this bug for the time being. It seems this problem is due to MTA/UMA newline conversion which is not a bug of PHP. Recent MTA/UMA do _not_ convert LF to CR/LF and this could results in errors like you have. It seems you are experiencing this issue and if this is the case, you should fix your code. i.e. Use CR/LF for new lines as defined in RFC. ------------------------------------------------------------------------ [2016-11-24 16:13:37] Sherwoodsports at gmail dot com This is on Windows server 2008. ------------------------------------------------------------------------ [2016-11-24 16:12:05] Sherwoodsports at gmail dot com I will modify and will send the output as soon as I can but am unable to for a day or two. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
