它不发送电子邮件。 我不想使用像PHPmailer，swiftmailer，hmailserver等外部库。
是否有人使用php邮件在Windows上发送电子邮件？ 我该怎么办？
编辑： 以下配置有效:( sendmail放在C：中）
php.ini =＆gt;
SMTP = smtp.gmail.com
smtp_port = 587
sendmail_from = ssmtpmailtesting@gmail.com
sendmail_path = "C:\sendmail\sendmail.exe"
sendmail.ini =＆gt;
smtp_server=smtp.gmail.com
smtp_port=587
smtp_ssl=auto
error_logfile=error.log
auth_username=ssmtpmailtesting@gmail.com
auth_password=[mypassword]
pop3_server=
pop3_username=
pop3_password=
force_sender=ssmtpmailtesting@gmail.com
force_recipient=
hostname=
答案 0 :(得分：2)
首先确保php.ini中的这两行是未注释的：
;SMTP = smtp.gmail.com
;smtp_port = 587 (or 465)
然后将smtp_ssl=auto更改为smtp_ssl=tls（因为RiggsFolly表示确保extension=php_openssl.dll已启用）。
此外，如果您使用的是Windows 8，请查看this主题或安装this代理。
