wp_mail() not working with "Name <email>" format in buggy PHP versions on Windows
|Reported by:||bbosh||Owned by:|
As a result of ticket #17305, wp_mail() accepts the $to parameter in the format "Name <email@…>".
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@example.com", "Test", "Test"); wp_mail("Name <firstname.lastname@example.org>", "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@…>>: "@" or "." expected after "Name" in C:\xampplite\htdocs\wp-includes\class-phpmailer.php on line 771
