Codeigniter $this->email->send() not working while mail() does - php

Question

I can't figure out why if I try to use the CI Email Class it doesn't send emails, while if I use the native PHP mail() Class works.
Has to be noted that sometimes I get "email sent" while is not actually sent and sometimes I get the error "my server is not setup".
I tried to figure out how to set it up but... nothing...
Controller code follows:
if($this->form_validation->run()){
//Set Language
$this->lang->load('site', $this->session->userdata('lang'));
//Random key
$user_valid_key = md5(uniqid());
//Prepare email
$this->load->library('email', array('mailtype' => 'html'));
$this->email->from($this->config->item('email_signup_from'), 'Wondermark.net');
$this->email->to($this->input->post('email'));
$this->email->subject($this->lang->line('email_signup_subject'));
//Format mail con %s per inserire i campi necessari
$signup_msg = sprintf($this->lang->line('email_signup_message'), $this->input->post('fname'), base_url().'main/signup_confirm/'.$user_valid_key);
$this->email->message((string)$signup_msg);
if($this->email->send()){
//TODO: load view...
echo "email sent";
}else{
$to = $this->input->post('email');
mail($to, 'test', 'Other sent option failed');
echo $this->input->post('email');
show_error($this->email->print_debugger());
}
//TODO: Add to db
}else{
// Form validation failed
}

Answer 1

Use this setup email..
$this->load->library('email');
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.gmail.com';
$config['smtp_port'] = '465';
$config['smtp_timeout'] = '7';
$config['smtp_user'] = 'sender_mailid#gmail.com';
$config['smtp_pass'] = 'password';
$config['charset'] = 'utf-8';
$config['newline'] = "\r\n";
$config['mailtype'] = 'text'; // or html
$config['validation'] = TRUE; // bool whether to validate email or not
$this->email->initialize($config);
$this->email->from('sender_mailid#gmail.com', 'sender_name');
$this->email->to('recipient#gmail.com');
$this->email->subject('Email Test');
$this->email->message('Testing the email class.');
$this->email->send();
echo $this->email->print_debugger();

I faced this problem and found the following solution. Just a little change in the email config and it's working 100%:
$config['protocol'] = 'ssmtp';
$config['smtp_host'] = 'ssl://ssmtp.gmail.com';

Codeigniter User Guide: https://www.codeigniter.com/user_guide/libraries/email.html
This setup works for me:
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'Your SMTP Server',
'smtp_port' => 25,
'smtp_user' => 'Your SMTP User',
'smtp_pass' => 'Your SMTP Pass',
'mailtype' => 'html'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
//Add file directory if you need to attach a file
$this->email->attach($file_dir_name);
$this->email->from('Sending Email', 'Sending Name');
$this->email->to('Recieving Email address');
$this->email->subject('Email Subject');
$this->email->message('Email Message');
if($this->email->send()){
//Success email Sent
echo $this->email->print_debugger();
}else{
//Email Failed To Send
echo $this->email->print_debugger();
}

I am using much time Run my configure code in localhost but it always gives me an error (Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.)
But when run this Below code in my server it works for me.
application>controller>Sendingemail_Controller.php
public function send_mail() {
$this->load->library('email');
$config = array();
$config['protocol'] = "smtp"; // you can use 'mail' instead of 'sendmail or smtp'
$config['smtp_host'] = "ssl://smtp.googlemail.com";// you can use 'smtp.googlemail.com' or 'smtp.gmail.com' instead of 'ssl://smtp.googlemail.com'
$config['smtp_user'] = "my#gmail.com"; // client email gmail id
$config['smtp_pass'] = "******"; // client password
$config['smtp_port'] = 465;
$config['smtp_crypto'] = 'ssl';
$config['smtp_timeout'] = "";
$config['mailtype'] = "html";
$config['charset'] = "iso-8859-1";
$config['newline'] = "\r\n";
$config['wordwrap'] = TRUE;
$config['validate'] = FALSE;
$this->load->library('email', $config); // intializing email library, whitch is defiend in system
$this->email->set_newline("\r\n"); // comuplsory line attechment because codeIgniter interacts with the SMTP server with regards to line break
$from_email = $this->input->post('f_email'); // sender email, coming from my view page
$to_email = $this->input->post('email'); // reciever email, coming from my view page
//Load email library
$this->email->from($from_email);
$this->email->to($to_email);
$this->email->subject('Send Email Codeigniter');
$this->email->message('The email send using codeigniter library'); // we can use html tag also beacause use $config['mailtype'] = 'HTML'
//Send mail
if($this->email->send()){
$this->session->set_flashdata("email_sent","Congragulation Email Send Successfully.");
echo "email_sent";
}
else{
echo "email_not_sent";
echo $this->email->print_debugger(); // If any error come, its run
}
}
and my view page where I defined f_email and email comes through post method.
application>view>emailtesting.php
<html>
<head>
<title> Send Email Codeigniter </title>
</head>
<body>
<?php
echo $this->session->flashdata('email_sent');
echo form_open('/Sendingemail_Controller/send_mail');
?>
<input type = "email" name = "f_email" placeholder="sender email id (from)" required />
<input type = "email" name = "email" placeholder="reciever email id (to)" required />
<input type = "submit" value = "SEND MAIL">
<?php
echo form_close();
?>
</body>
if some error comes again please visit official documentation below:

After fighting with this same problem for a couple hours I finally decided to change my config to send through a different server. My original server for some reason would send to some addresses but not others (in same domain). As soon as I changed to sendgrid it worked as expected.
If you are not getting the results you expect, try a different smtp server. The problem may not be your code...

Answer 6

I had the same problem and I try below code instead of Codeignitor's mail function.
mail('mypersonalmail#domainserver.com' , 'Test', 'Test Email');
It works and mail is send to the email address. That mail has sent by already created email address (As i think). In my case it is:
gtt28651ff#p3plcpnl0552.srod.ahx3.domainserver.com
So I copy this email address and try it with below code.
$this->email->from('gtt28651ff#p3plcpnl0552.srod.ahx3.domainserver.com', 'www.domainserver.com');
And it work fine. It seems to be some servers need already created email address to send the email while others are NOT.
Hope this is clear and helpful.

Lately, sending emails through Google SMTP can be very tricky due to their security checks.
Verify if:
you have the rDNS on your server and it's matching your server IP
disable the 2-step auth on the email you are using to send emails from (on Google settings)
have IMAP and POP enabled on the email you are using to send emails from (on Google settings)
allow less secure apps on the email you are using to send emails from (on Google settings)
Change the CI settings as follows:
//Google settings for CI
$config['protocol'] = 'ssmtp'; //smtp not working
$config['smtp_host'] = 'ssl://ssmtp.gmail.com'; //notice ssmtp
$config['smtp_user'] = 'anyemail#server.com'; //must use Google
$config['smtp_pass'] = '***********';
$config['smtp_port'] = '465';
$config['smtp_crypto'] = 'ssl';
//general settings
$config['_smtp_auth'] = TRUE; //important
$config['smtp_timeout'] = 30;
$config['charset'] = 'utf-8';
$config['mailtype'] = 'html';
//optional
$config['wrapchars'] = 76;
$config['wordwrap'] = TRUE;
I hope this will save you the 2 days I have struggled with this issue.

I've spent hours trying to change the port,enabling the ssl extension in php.ini file etc nothing worked only ended up in a message SMTP server is not configured properly.I use WAMP as a localhost,when i turn off my antivirus avast the same config worked!!! the was send successfully.so it may be your antivirus program blocking on a local machine.
