What if mac php fails to send mail?

The question shows:

Fatal: open lock file pid/master.pid: unable to set exclusive lock: Resource temporarily unavailable problem.

Solution:

Take a look at the php.ini file and make sure you can see this line:

Sendmail_path = sendmail-t-I

Or

Sendmail_path = / usr/sbin/sendmail-t-I

It should not have any quotation marks, and there is no semicolon (;) before it. If it does not exist or is different, change it to match the above line.

If that doesn't help, look at http://switch.richard5.net/2006/08/19/fatal-open-lock-file-pidmasterpid/ and see if it helps. Now that you have updated PHP, I suspect that postfix is a problem.

In addition:

You may have a suffix configuration problem. If the email you are trying to send is not from the local server, you may need to check / etc/mailnames and / etc/postfix/main.cf checks myhostname,mydomain and myorigin.
