配置以及实现mail()函数
1、下载sendmail
在百度自行搜索sendmail软件
2、解压安装包(最好和php同一个目录下C:\websoft\)

3、配置php.ini文件
[mail function]
; For Win32 only.
SMTP = smtp.jhonse.com
smtp_port = 25
; For Win32 only.
sendmail_from = service@jhonse.com
; For Unix only. You may supply arguments as well (default: “sendmail -t -i”).
sendmail_path = "C:\websoft\sendmail\sendmail.exe -t"

4、配置sendmail.ini文件
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=service@jhonse.com
auth_password=123456
; if your smtp server uses pop3 before smtp authentication, modify the
; following three lines. do not enable unless it is required.
pop3_server=
pop3_username=
pop3_password=
; 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=service@jhonse.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

5、说明: 第一次最好启用debug.log_file,error_logfile,以查看sendmail是否生效。
6、重启apache或者IIS
重启之后,mail()函数就可以正常发送邮件了。
