I'm trying to send an email via PHP with HTML attributes, an email formatted with images and styles. I have tried using PHPMailer, but without success, I have used PHP's mail () function that meets my needs and sends the email without many problems, the only problem in itself is that the email is not authenticated and lives falling in quarantine, can I take action to correct this? Another problem, my main is that the email does not send when I try to put tags like <div style="text-align: center; margin: 0 auto;"></div> and also when I try to add images with <img src='http://meusite.com.br/templates-email/cabecalho.jpg' alt='img' /> (just an example).

The question is:

How to send HTML emails using the mail () function (including images in this email and divs). ?

How to troubleshoot e-mail authenticity (live quarantined).

TRY 1 (do not send).

//envia e-mail de confirmação
    $email_remetente = "[email protected]";
    $headers = "MIME-Version: 1.1\n";
    $headers .= "Content-type: text/HTML; charset=utf-8\n";
    $headers .= "From: $email_remetente\n"; // remetente
    $headers .= "Return-Path: $email_remetente\n"; // return-path
    $headers .= "Reply-To: $email_usuario\n"; // Endereço (devidamente validado) que o seu usuário informou no contato
    $texto_mensagem = "<html><head><title>Blue Contract - Ative sua conta</title></head><body>";
    $texto_mensagem .= "<div style=\'font: 14px Arial, Tahoma; text-align: center; margin: 0 auto;\'>";
    $texto_mensagem .= "<img src='http://bluecontract.com.br/templates-email/cabecalho.jpg' alt='img' />";
    $texto_mensagem .= "<h1>Ativação de conta - Blue Contract</h1>";
    $texto_mensagem .= "<p>Através de nosso website, você efetuou um cadastro em ".$usuDataCadastro."</p>";
    $texto_mensagem .= "<p>Agora, para finalizar seu cadastro é necessário confirmar sua conta.</p>";
    $texto_mensagem .= "</div>";
    $texto_mensagem .= "</body></html>";

    $envio = mail(base64_decode($usuEmail), "Blue Contract - Ative sua conta", $texto_mensagem, $headers, "-f$email_remetente");

    // Exibe uma mensagem de resultado
    if ($envio) { } else { header("Location: ".URL."criar-conta?tk=".$usuToken."&eee#ve"); exit(); }

ATTEMPT 2

    //envia e-mail de confirmação
        $email_remetente = "[email protected]";
        $headers = "MIME-Version: 1.1\n";
        $headers .= "Content-type: text/HTML; charset=utf-8\n";
        $headers .= "From: $email_remetente\n"; // remetente
        $headers .= "Return-Path: $email_remetente\n"; // return-path
        $headers .= "Reply-To: $email_usuario\n"; // Endereço (devidamente validado) que o seu usuário informou no contato

        $texto_mensagem = "<html>
                            <head>
                               <title>Blue Contract - Ative sua conta</title>
                            </head>

                            <body>
                            <div style=\'margin: 40px auto; margin-left: auto; margin-right: auto; text-align: center;\'>
                                <img src=\'http://bluecontract.com.br/templates-email/cabecalho.jpg\' width=\'100%\'/>
                            </div>
                            E-mail: <b>[email protected]</b>
                            </body></html>";

         $envio = mail(base64_decode($usuEmail), "Blue Contract - Ative sua conta", $texto_mensagem, $headers, "-f$email_remetente");

         // Exibe uma mensagem de resultado
         if ($envio) { } else { header("Location: ".URL."criar-conta?tk=".$usuToken."&eee#ve"); exit(); }

I tried to do these two ways, both with the same image problem.

Remembering email sending happens , then my problem is not that emails do not reach the destination .

I think the question is merely syntax error because your HTML should be sending a lot of backslashes wrongly. Probably this will solve:

$texto_mensagem = '
   <html>
      <head>
         <title>Blue Contract - Ative sua conta</title>
      </head>
      <body>
      <div style="margin: 40px auto; margin-left: auto; margin-right: auto; text-align: center;">
         <img src="http://bluecontract.com.br/templates-email/cabecalho.jpg"width="100%" />
      </div>
      E-mail: <b>[email protected]</b>
      </body>';

Or better yet, using HEREDOC :

HEREDOC

$texto_mensagem = <<<FINAL
   <html>
      <head>
         <title>Blue Contract - Ative sua conta</title>
      </head>
      <body>
      <div style="margin: 40px auto; margin-left: auto;
         margin-right: auto; text-align: center;">
         <img src="http://bluecontract.com.br/templates-email/cabecalho.jpg"width="100%" />
      </div>
      E-mail: <b>[email protected]</b>
      </body>
 FINAL;

In addition, their headers must be separated by CR LF, (\ r \ n), ie chr( 13 ) . chr( 10 ) :

$crlf = chr(13).chr(10) //coloquei em variável apenas para facilitar testes
$headers = "MIME-Version: 1.1".$crlf;
$headers .= "Content-type: text/HTML; charset=utf-8".$crlf;
$headers .= "From: $email_remetente".$crlf; // remetente
$headers .= "Return-Path: $email_remetente".$crlf; // return-path
$headers .= "Reply-To: $email_usuario".$crlf; //

And to help debug , you may want to replace base64_decode with a literal address for tests.

About authenticity of emails

One of the things that can help is to examine the headers of the original received by the part, to analyze the reasons for the lock. One likely improvement would be to add SPF records to the domain's DNS server, authorizing the machine that sends the emails as trusted.

Example: allowing any IP to be sent between 192.168.0.1 and 192.168.255.255:

"v=spf1 ip4:192.168.0.1/16 -all"

Just add a TXT entry with the above data, for example. Do not forget to include all possible valid email sources in the domain in the rules. The subject deserves further study.

I was able to resolve my issue through PHP Mailer . First of all you should download PHP Mailer and unzip it inside the folder of your project, soon afterwards do not forget to include it in your .php file

<?php
require_once("phpmailer/class.phpmailer.php"); // requer a class do PHPMAILER

//envia e-mail de confirmação
$usuEmail = "[email protected]"; // email para onde será enviado (destinatário)
$usuNome = "João da Silva"; // nome para quem será enviado (destinatário)

$mail = new PHPMailer();
$mail->isSMTP();  // send via SMTP
$mail->Host = 'mail.seusite.com.br'; //Endereço do seu Servidor de Email
$mail->SMTPAuth = true; // true se o email é autenticado
$mail->Port = '587'; // Porta para autenticação smtp geralmente é a 587;
$mail->Username = '[email protected]'; // Seu endereço de email que envia os email
$mail->Password = "SUA_SENHA"; // senha do usuário que envia o email

$mail->From = '[email protected]'; //a pessoa que ta enviando o email

$mail->FromName = 'NOME DO REMETENTE (ASSUNTO)'; //Nome de quem ta enviando...
$mail->AddAddress($usuEmail, $usuNome); //e-mail, nome
$mail->AddReplyTo("[email protected]", "NOME DO MEU SITE/EMAIL"); //e-mail para respostas e nome do site ou email que receberá respostas

$mail->WordWrap = 50; // Quebra de linha
$mail->IsHTML(true); // Se for true é enviando email no formato HTML
$mail->Subject = "ASSUNTO DO EMAIL"; //Assunto do seu Email
$mail->Body = utf8_decode("
<meta charset='utf-8'/>
<body>
<div style='min-height: 250px;'>
    <div style='font: 14px Arial, Tahoma; padding: 0 0 30px 0; text-align: center; margin: 0 auto; border: 1px solid #d9d9d9; border-radius: 5px;'>
        <img src='cid:cabecalho' width='100%'/>
        <h1>Ative sua conta</h1>
        <p>Através de nosso website, você efetuou um cadastro.</p>
        <p>Agora, para finalizar seu cadastro é necessário confirmar sua conta.</p>
        <br><a href='#' style='background: #006699; padding: 10px 20px 10px 20px; margin: 10px auto; color: #fff; text-decoration: none; font-weight: bold;'>Ative sua conta</a>
        <br>
        <p>Caso não esteja conseguindo utilizar este botão, copie e cole o link abaixo em seu navegador:</p><pre>meusite.com.br/ativar-conta </pre>

        <img src='cid:rodape' width='100%'/>

    </div>
</div>
</body>

"); //Conteudo HTML
$mail->AltBody = "Para mensagens somente texto"; //Somente Texto

//adiciona arquivos em anexo
$mail->AddEmbeddedImage('pasta_da_imagem/cabecalho.jpg', 'cabecalho');
$mail->AddEmbeddedImage('pasta_da_imagem/rodape.jpg', 'rodape');

$envio = $mail->Send(); //envia o e-mail

// Limpa os destinatários e os anexos
$mail->ClearAllRecipients();
$mail->ClearAttachments();

// Exibe uma mensagem de resultado
if ($envio) { echo "enviado"; } else { echo "O e-mail não pode ser enviado, ocorreu um erro"; }

//
?>

The functional code is above, below you will find just the explanation of how to customize it and how it works.

How is the attachment of the files in the e-mail done?

It is a very simple solution, if you analyze well you will see that the whole file attachment can be done with just one line of code:

//adiciona arquivos em anexo
$mail->AddEmbeddedImage('pasta_da_imagem/cabecalho.jpg', 'cabecalho');
$mail->AddEmbeddedImage('pasta_da_imagem/rodape.jpg', 'rodape');

If you want to add more attachments, simply repeat the line by changing the name of the file and its name. Ex: $mail->AddEmbeddedImage('pasta_da_imagem/meuarquivo.jpg', 'nome_do_arquivo');

How to use in the HTML attachment?

For this you only use cid:nome_do_arquivo , remembering that after the colon : you will put the name that you called your file when appending it in the email.

I do not want to leave the password exposed

If you want to avoid leaving the password exposed in the file, use some non-one-way encodings, even though simple ones can make it difficult for laypeople and the password is not easily displayed. A good example is base64_encode() You can use something like:

$mail->Password = base64_decode("SUA_SENHA_CRIPTOGRAFADA_COM_BASE64_ENCODE");
