lampp restart required to send php script mail from server

[rajshardel]

my lampp configuration requires restart once after boot to send php script mail from server. Otherwise without restart mail from server to gmail and gmail to server is working but php script mail shows error.

I am using postfix and dovecot and they are both started at boot and also saslauth is started at boot.

There is no log showing in mail but after lampp restart uid nobody is generated then php script mail is sent out.

What could be wrong.

PHP Version 5.4.7

Apache/2.4.3 (Unix) OpenSSL/1.0.1c PHP/5.4.7

Apache api version 20120211

OS is centos 6. 4
