PHP 5.3.13 and as noted IIS 7.5. PHP mail() was working fine until I did 3 things (at the same time). (a) added memory to the server taking it from 4gb to 5gb; (b) ran Windows Update and applied all available updates; (c) removed SQL server installation.
Windows 2008 R2 SMTP server still works fine. I know this because I can drop a file in the pickup folder and the mail is delivered.
This PHP test script:
<?php $to='my_name@another_domain.com'; $subject='Test email using PHP'; $message='This is a test email message'. "\r\n"; $headers='From:email@example.com' . "\r\n" . 'Reply-To:firstname.lastname@example.org' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); mail($to, $subject, $message, $headers, '-email@example.com'); ?>
creates this entry in the PHP log file:
mail() on [C:\www\pgs.com\store\admin\test_php_mail.php:1]: To: my_name@another_domain.com -- Headers: From:firstname.lastname@example.org Reply-To:email@example.com X-Mailer: PHP/5.3.13
When using PHP now, I never see a file dropping on the IIS pickup folder. And on other thing, when using previouly working features on the site (such as password recovery), there is no entry made in the mail.log. (The mail log has just been setup to help solve this problem.)
How do I fix this? Or at least how do I diagnose the problem? Thanks.
