Message was not sent.Mailer error: SMTP connect() failed

问题

I'm new in Php and find a Php mailer class to send email but getting following error.

Error Message:

Message was not sent.Mailer error: SMTP connect() failed.

Php Code:

<?php
require("class.phpmailer.php");

$mail = new PHPMailer();

$mail->IsSMTP();  // telling the class to use SMTP
$mail->Host     = "smtp.impeccableplus.com"; // SMTP server

$mail->From     = "from@example.com";
$mail->AddAddress("email@gmail.com");

$mail->Subject  = "First PHPMailer Message";
$mail->Body     = "Hi! \n\n This is my first e-mail sent through PHPMailer.";
$mail->WordWrap = 50;

if(!$mail->Send()) {
echo 'Message was not sent.';
echo 'Mailer error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent.';
}

?>

Thanks.

Update:

I just change the host name = localhost. Now it's successfully sent email but problem is, It's showing the mail in spam folder. Why ?

回答1:

There could be a number of reasons for this:

Your SMTP server smtp.impeccableplus.com could be blacklisted. You can check if your SMTP server is being blacklisted
The from address could be regarded as spammy, especially if you're using from@example.com
Some mail clients (such as Gmail) do not like the fact that you are sending an email "from" someone else's address if it really didn't originate from that address
and possibly 20+ other reasons

You should consider setting up SPF and DKIM for your email address that you are sending emails from. Read this and this. By Setting up SPF and DKIM, you are essentially authenticating the email which considerably improves mail delivery.

Alternatively, if you really get stuck, consider using a mail delivery API such as Sendgrid.
