pop3: disabling set_time_out() for Postie plugin to work

I updated Postie plugin, and it stop running. I don’t know why the previews release worked. But now i’m having a stop:

PHP Error Message

Warning: set_time_limit() has been disabled for security reasons in /home/a2080612/public_html/wordpress/wp-includes/class-pop3.php on line 68

This is caused by my webserver, that has set_time_out() function disabled. So, can i just delete some part of the class-pop3.php code? This is it:

if(!empty($timeout)) {
settype($timeout,”integer”);
$this->TIMEOUT = $timeout;
if (!ini_get(‘safe_mode’))
set_time_limit($timeout);
}
return true;
}

function update_timer () {
if (!ini_get(‘safe_mode’))
set_time_limit($this->TIMEOUT);
return true;
}
