Ребят подскажите пожалуйста в чем может быть причина, первый раз пытаюсь настроить почту на локалке под Windows. Использую sendmail.

Вот конфиг sendmail

; configuration for fake sendmail

; if this file doesn't exist, sendmail.exe will look for the settings in
; the registry, under HKLM\Software\Sendmail

[sendmail]

; you must change mail.mydomain.com to your smtp server,
; or to IIS's "pickup" directory.  (generally C:\Inetpub\mailroot\Pickup)
; emails delivered via IIS's pickup directory cause sendmail to
; run quicker, but you won't get error messages back to the calling
; application.

smtp_server=smtp.mail.ru

; smtp port (normally 25)

smtp_port=25

; SMTPS (SSL) support
;   auto = use SSL for port 465, otherwise try to use TLS
;   ssl  = alway use SSL
;   tls  = always use TLS
;   none = never try to use SSL

smtp_ssl=auto

; the default domain for this server will be read from the registry
; this will be appended to email addresses when one isn't provided
; if you want to override the value in the registry, uncomment and modify

default_domain=mail.ru

; log smtp errors to error.log (defaults to same directory as sendmail.exe)
; uncomment to enable logging

error_logfile=error.log

; create debug log as debug.log (defaults to same directory as sendmail.exe)
; uncomment to enable debugging

debug_logfile=debug.log

; if your smtp server requires authentication, modify the following two lines

auth_username=мой ящик@mail.ru
auth_password=пароль от ящика

; if your smtp server uses pop3 before smtp authentication, modify the 
; following three lines.  do not enable unless it is required.

pop3_server=pop.mail.ru
pop3_username=мой ящик@mail.ru
pop3_password=пароль от ящика

; force the sender to always be the following email address
; this will only affect the "MAIL FROM" command, it won't modify 
; the "From: " header of the message content

force_sender=мой ящик@mail.ru

; force the sender to always be the following email address
; this will only affect the "RCTP TO" command, it won't modify 
; the "To: " header of the message content

force_recipient=

; sendmail will use your hostname and your default_domain in the ehlo/helo
; smtp greeting.  you can manually set the ehlo/helo name if required

hostname=mail.ru

Вот что правил в php.ini

[mail function]
; For Win32 only.
; http://php.net/smtp
;SMTP = localhost
; http://php.net/smtp-port
;smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "D:\Server Files\sendmail\sendmail.exe -t"

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
;mail.force_extra_parameters =

; Add X-PHP-Originating-Script: that will include uid of the script followed by the filename
mail.add_x_header = On

; The path to a log file that will log all mail() calls. Log entries include
; the full path of the script, line number, To address and headers.
;mail.log =
; Log mail to syslog (Event Log on NT, not valid in Windows 95).
;mail.log = syslog

А вот собственно простейший код на PHP для теста отправки письма

<?php

	$to  = 'мой ящик@yandex.ru';

	$subject = 'Тестовый заголовок';

	$message = 'Тестовое сообщение';

	$headers  = "Content-Type: text/plain; charset=UTF-8\r\n";
	$headers .= "From: Например Андрей <admin@site.ru>\r\n";

	if(mail($to, $subject, $message, $headers)){
		echo 'Письмо отправлено!';
	}

?>

Скрипт отрабатывает нормально без ошибок, sendmail вообще не создает лог файлы, почта не отправляется. В чем может быть причина?
