sendmail.ini配置如下

[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.qq.com

; 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=mydomain.com

; 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=qq号@qq.com

auth_password=qq邮箱原密码

; if your smtp server uses pop3 before smtp authentication, modify the 

; following three lines.  do not enable unless it is required.

pop3_server=smtp.qq.com

pop3_username=qq号@qq.com

pop3_password=邮箱开启pop3给的密码

; 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=qq号@qq.com

; 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=qq号@qq.com

php.ini配置如下：

[mail function]

; For Win32 only.

; http://php.net/smtp

SMTP = smpt.qq.com

; http://php.net/smtp-port

smtp_port = 25

; For Win32 only.

; http://php.net/sendmail-from

sendmail_from = qq号@qq.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").

; http://php.net/sendmail-path

sendmail_path = “E:\sendmail\sendmail.exe -t”

代码如下：

<?php

error_reporting(-1);

ini_set('diaplay_errors', 0);

ini_set('log_errors',-1);

error_log('被攻击了！',1,'qq号@qq.com');
