23243,"wp_mail() not working with ""Name <email>"" format in buggy PHP versions on Windows",bbosh,,"As a result of ticket #17305, wp_mail() accepts the $to parameter in the format ""Name <email@domain.com>"".

There exists a PHP bug in versions below 5.2.11 and in 5.3, on Windows. This bug occurs when addresses are passed to the PHP mail() function in the ""Name <email>"" format and prevents e-mails from being sent. I believe this bug in fixed in 5.3.1 and above. (see https://bugs.php.net/bug.php?id=28038)

I don't believe this affects any core functionality, but may affect some plugins which pass $to in the above format.

I tested in PHP 5.2.4 on Windows with the following code:

{{{
wp_mail(""email@ext.com"", ""Test"", ""Test"");
wp_mail(""Name <email@ext.com>"", ""Test 2"", ""Test 2"");
}}}

The first email is received; the second isn't. When removing error suppression from the mail() calls in class-phpmailer.php, the following warning is outputted:

  Warning: mail() [function.mail]: SMTP server response: 501 <Name <email@ext.com>>: ""@"" or ""."" expected after ""Name"" in C:\xampplite\htdocs\wp-includes\class-phpmailer.php on line 771",defect (bug),new,normal,Awaiting Review,Mail,3.5,minor,,,ian_dunn@…
