I used to be able to send email using the simple mail() in PHP although since I have upgraded to the latest PHP I am unable to send emails.

When I look at the email log I get the following:

    To fix the fatal: open lock file pid/master.pid: unable to set exclusive lock: Resource temporarily unavailable problem:

    Have a look at your php.ini file and make sure that you can see this line:

    sendmail_path = sendmail -t -i

    or

    sendmail_path = /usr/sbin/sendmail -t -i

    It shouldn’t have any quotes around it and that there is not semi-colon (;) before it. If it’s not there or different, change it to match one of the line above.

    If that doesn’t help, have a look at http://switch.richard5.net/2006/08/19/fatal-open-lock-file-pidmasterpid/ and see if that helps. Since you’ve updated PHP, I doubt that postfix is the problem but you never know.

    Also:

    You may have postfix configuration issues. It’s trying to deliver using the local relay. If the e-mail your trying to send to isn’t one on the local server, you might want to check your /etc/mailnames and in /etc/postfix/main.cf check myhostname, mydomain and myorigin.
