mac php failed to send email What should I do?

The problem 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 shouldn’t There are no quotation marks and there is no semicolon (;) before it. If it doesn't exist or is different, change it to match the line above.

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

Also:

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