我正在尝试从我的codeigniter项目中发送电子邮件，并且命令 echo $this->email->print_debugger(); 一直返回以下内容：
220 smtp.gmail.com ESMTP q139sm4099547wmd.2 - gsmtp
你好：250-smtp.gmail.com为你服务，[41.228.226.174] 250-SIZE 35882577 250-8BITMIME 250-STARTTLS 250 ENHANCEDSTATUSCODES 250流水 250 SMTPUTF8 无法发送AUTH LOGIN命令。错误：530 5.7.0必须 首先发出STARTTLS命令。 q139sm4099547wmd.2 - gsmtp无法使用 使用PHP SMTP发送电子邮件。您的服务器可能未配置为发送 邮件使用这种方法。
所以我回去试图用一个简单的PHP代码发送电子邮件，没有codeigniter，结果发现最初的问题与代码服务器无关，因为我再次失败了。 这是我的PHP代码：
<?php
$to = '**********@gmail.com';
$subject = 'Testing sendmail.exe';
$message = 'Hi, you just received an email using sendmail!';
$headers = 'From: ******@gmail.com' . "\r\n" .
'MIME-Version: 1.0' . "\r\n" .
'Content-type: text/html; charset=utf-8';
if(mail($to, $subject, $message, $headers))
echo "Email sent";
else
echo "Email sending failed";
?>
这里是php.ini中的邮件配置，对于记录，我尝试了以下函数，其中smtp_port = 25行和sendmail_from = ********@gmail.com注释（带有初始“;”）并且没有“ ;”因为我在尝试解决问题时在论坛中阅读了这个建议。
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = smtp.gmail.com
; http://php.net/smtp-port
smtp_port = 25
; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = ********@gmail.com
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path="C:\wamp\sendmail\sendmail.exe -t -i"
我也尝试删除行sendmail_path=.....
最后这是我的sendmail.ini：
; 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=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=
; 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=
; 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=***********@gmail.com
auth_password=*******************
; 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=************@gmail.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=
; 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=localhost
任何帮助都会受到高度赞赏，因为我花了3天时间试图解决这个问题无济于事。
编辑：第二个代码确实返回“已发送电子邮件”，但即使在垃圾邮件中也无法找到它。是的，我已经将gmail配置为“允许不太安全的应用程序”

您的电子邮件发送部分是正确的。没问题。
如果您要发送邮件，则必须正确配置电子邮件设置。
答案 1 :(得分：0)
您的电子邮件代码没问题，但如果您使用的是wamp服务器.....需要更改以下内容...
"C:\wamp\bin\php\php5.5.12\php.ini"上设置 sendmail_path php.ini 文件
"C:\wamp\bin\apache\apache2.4.9\bin\php.ini" ** sendmail_path =＆＃34; C：\ wamp \ sendmail \ sendmail.exe -t＆＃34;
我认为它会奏效。

在config / email.php中，我不得不添加
$ config ['smtp_crypto'] =“tls”;
