我在Windows上使用apache，php和sendmail.exe。 我下载sendmail.exe并将其配置如下：
; 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.gmail.com
; smtp port (normally 25)
smtp_port=587
; 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=domain.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=admin@whilgeek.com
auth_password=19910610
; if your smtp server uses pop3 before smtp authentication, modify the
; following three lines
pop3_server=
pop3_username=
pop3_password=
; to force the sender to always be the following email address, uncomment and
; populate with a valid email address. this will only affect the "MAIL FROM"
; command, it won't modify the "From: " header of the message content
force_sender=webmaster@domain.com
; 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=
我的php.ini中的电子邮件功能是这样的：
[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25
; For Win32 only.
sendmail_from = admin@whilgeek.com
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path =C:\usr\lib\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 =
我在计算机中使用userCake1.4（download form here），并说成功发送了电子邮件。但我没有收到发送给我的gamil的电子邮件。
有什么不对？
答案 0 :(得分：0)
我认为你的问题是反向DNS查询。当您从服务器发送电子邮件时，您的服务器必须连接到Internet，反向DNS查找必须指向您的服务器。
例如，mail.example.com的地址（A）记录指向IP地址192.0.2.5。在反向数据库的指针记录中，此IP地址存储为域名5.2.0.192.in-addr.arpa，指向其指定的主机名mail.example.com。
