POPHP mail() function not returning true or false - script just times out
text
Body
copied!<p>The php mail function has stopped working on a Centos 5.7 server. The scripts containing the function call were working on this server until the last couple of days but there have not been any configuration changes..</p> <p>Whenever I call the mail() function the PHP script just stalls/freezes on that line until it reaches the script timeout limit.</p> <pre><code>$msgheader = 'MIME-Version: 1.0' . "\r\n"; $msgheader .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; $msgheader .= "From: Test Name <no-reply@servername.com>\r\n"; echo "About to send mail ->"; mail ("test@servername.com", "Test Subject", "Test Body", $msg_header); echo "Script never reaches this line!"; </code></pre> <p>I have modified the email addresses for this question, but I know they are not the issue as the script executed correctly previously.</p> <p>I have tried changing the email address to various personal accounts (e.g. @yahoo.com) and it still doesn't work, so I don't think this is due to spam filtering at the organization where my users reside.</p> <p>What could be causing the mail function to get stuck until the script timeout rather than just immediately return false if it can't send the email? What settings can I look at?</p> <p>Thanks!</p> <p><strong>EDIT:</strong></p> <ul> <li>There are no errors in the Apache error logs</li> <li><p>php.ini has:</p> <p>SMTP = localhost; smtp_port = 25; sendmail_path = /usr/sbin/sendmail -t -i</p></li> </ul>
