Unable to send email in php - php

Question

I am trying following code to send mail
but it is showing
Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
and gmail is informing me that Sign-in attempt prevented
<?php
require 'PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = 'sss#gmail.com';
$mail->Password = '*******';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->From = 'abc#gmail.com';
$mail->FromName = 'asdf ';
$mail->addAddress('abc#gmail.com', 'sadf ');
$mail->WordWrap = 50;
$mail->isHTML(true);
$mail->Subject = "Using PHPMailer";
$mail->Body = "Hi Iam using PHPMailer library to sent SMTP mail from localhost";
if(!$mail->send()) {
echo "Message could not be sent.";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}
echo "Message has been sent";
?>
How to resolve above problem?

Answer 1

Try the following steps:
enable debug mode to catch possible errors
$mail->SMTPDebug = 1;
enable SMTP authentication
$mail->SMTPAuth = true;
also check for SSL support in php configuration file (php.ini)
extension=php_openssl.dll

Answer 2

You need set permission for send mail with gmail.
- Login Google Account
- Go Privacy Page
- Allow third party apps
After try this code:
$mail = new PHPMailer();
$body = file_get_contents('contents.html');
$body = eregi_replace("[\]",'',$body);
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "mail.yourdomain.com"; // SMTP server
$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
// 1 = errors and messages
// 2 = messages only
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "tls"; // sets the prefix to the servier
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 587; // set the SMTP port for the GMAIL server
$mail->Username = "yourusername#gmail.com"; // GMAIL username
$mail->Password = "yourpassword"; // GMAIL password
$mail->SetFrom('name#yourdomain.com', 'First Last');
$mail->AddReplyTo("name#yourdomain.com","First Last");
$mail->Subject = "PHPMailer Test Subject via smtp (Gmail), basic";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->MsgHTML($body);
$address = "whoto#otherdomain.com";
$mail->AddAddress($address, "John Doe");
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}

Answer 3

Since you are getting email from Google, it describes the email is trying to send but it is blocked by Google. Do the following steps.
I hope this helps.
Check if IMAP is enabled
Check here and enable less secure apps
Display Unlock Captcha

Answer 4

change the following in your code
isSMTP() to IsSMTP() , addAddress() to AddAddress() & isHTML() to IsHTML().
and yes check the ports also. sometoimes port also off which do not let connection to be established.
Hope it will work!

I think you have to enable POP and IMAP in you gamil. Try this
Sign in to Gmail
Click the gear in the top right.
Select Settings.
Click Forwarding and POP/IMAP.
Select Enable IMAP.
Click Save Changes.
<?
$account="email_address#gmail.com";
$password="accountpassword";
$to="mail#subinsb.com";
$from="email_address#gmail.com";
$from_name="Name";
$msg="<strong>This is a bold text.</strong>"; // HTML message
$subject="Database Backup";
/*End Config*/
include("phpmailer/class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth= true;
$mail->Port = 465; // Or 587
$mail->Username= $account;
$mail->Password= $password;
$mail->SMTPSecure = 'ssl';
$mail->From = $from;
$mail->FromName= $from_name;
$mail->isHTML(true);
$mail->Subject = $subject;
$mail->Body = $msg;
$mail->addAddress($to);
if(!$mail->send()){
echo "Mailer Error: " . $mail->ErrorInfo;
}else{
echo "E-Mail has been sent";
}
?>
