I have trouble sending email in PHP. I get an error: SMTP server response: 530 SMTP authentication is required.

I was under the impression that you can send email without SMTP to verify. I know that this mail will propably get filtered out, but that doesn't matter right now.

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = someonelse@example.com

This is the setup in the php.ini file. How should I set up SMTP? Are there any SMTP servers that require no verification or must I setup a server myself?

When you are sending an e-mail through a server that requires SMTP Auth, you really need to specify it, and set the host, username and password (and maybe the port if it is not the default one - 25).

For example, I usually use PHPMailer with similar settings to this ones:

$mail = new PHPMailer();

// Settings
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';

$mail->Host       = "mail.example.com"; // SMTP server example
$mail->SMTPDebug  = 0;                     // enables SMTP debug information (for testing)
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Port       = 25;                    // set the SMTP port for the GMAIL server
$mail->Username   = "username"; // SMTP account username example
$mail->Password   = "password";        // SMTP account password example

// Content
$mail->isHTML(true);                                  // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

$mail->send();

PHP mail() and SMTP Authentication - Knowledgebase, When you are sending an e-mail through a server that requires SMTP Auth, you really need to specify it, and set the host, username and password (and maybe  When you use the PHP mail function, you are sending email directly from your web server. This can cause issues if the FROM address isn’t set properly or if your email isn’t hosted with DreamHost. Sending mail via SMTP is recommended as email is sent from the mail server rather than the web server.

<?php
ini_set("SMTP", "aspmx.l.google.com");
ini_set("sendmail_from", "YOURMAIL@gmail.com");

$message = "The mail message was sent with the following mail setting:\r\nSMTP = aspmx.l.google.com\r\nsmtp_port = 25\r\nsendmail_from = YourMail@address.com";

$headers = "From: YOURMAIL@gmail.com";

mail("Sending@provider.com", "Testing", $message, $headers);
echo "Check your email now....&lt;BR/>";

Sending email with PHP from an SMTP server, Overview When you use the PHP mail function, you are sending email directly from your web server. This can cause issues if the FROM The other side of the PHP mail function () is that the email is sent from your web server, which may cause issues with deliverability due to security concerns such as suspicion of spam and blacklisting. The best way to overcome this problem is sending messages via an SMTP server, however,

For Unix users, mail() is actually using Sendmail command to send email. Instead of modifying the application, you can change the environment. msmtp is an SMTP client with Sendmail compatible CLI syntax which means it can be used in place of Sendmail. It only requires a small change to your php.ini.

sendmail_path = "/usr/bin/msmtp -C /path/to/your/config -t"

Then even the lowly mail() function can work with SMTP goodness. It is super useful if you're trying to connect an existing application to mail services like sendgrid or mandrill without modifying the application.

How to Send an Email via Gmail SMTP Server using PHP, PHP mail() does not usually allow you to use the external SMTP server and it does not support SMTP  PHP provides a mail() function which used to send an email. But there are limitations while using mail() method. You can’t send email from a local development server. Another drawback is, there is a high possibility of your email ended up into a Spam folder. To get out of these problems,

The problem is that PHP mail() function has a very limited functionality. There are several ways to send mail from PHP.

  1. mail() uses SMTP server on your system. There are at least two servers you can use on Windows: hMailServer and xmail. I spent several hours configuring and getting them up. First one is simpler in my opinion. Right now, hMailServer is working on Windows 7 x64.
  2. mail() uses SMTP server on remote or virtual machine with Linux. Of course, real mail service like Gmail doesn't allow direct connection without any credentials or keys. You can set up virtual machine or use one located in your LAN. Most linux distros have mail server out of the box. Configure it and have fun. I use default exim4 on Debian 7 that listens its LAN interface.
  3. Mailing libraries use direct connections. Libs are easier to set up. I used SwiftMailer and it perfectly sends mail from Gmail account. I think that PHPMailer is pretty good too.

No matter what choice is your, I recommend you use some abstraction layer. You can use PHP library on your development machine running Windows and simply mail() function on production machine with Linux. Abstraction layer allows you to interchange mail drivers depending on system which your application is running on. Create abstract MyMailer class or interface with abstract send() method. Inherit two classes MyPhpMailer and MySwiftMailer. Implement send() method in appropriate ways.

Comments
  • +1 for phpMailer -- its the sane persons alternative to PHP's built in mail() function.
  • It's worth noting for those stumbling on this answer that PHPMailer is also built into WordPress and can be configured using the 'phpmailer_init' action hook. It's a convenient way to set up WordPress for SMTP mail or Amazon SES (which supports SMTP connections).
  • Is PHP Mailer allowed to be used in paid scripts?
  • @Luka Yes, it is. According to their license file PHPMailer uses the LGPL 2.1 license, which allows commercial usage.
  • Do I need to do anything special to use this code? Where do I put this? Can I call it with an HTML5 form with a POST request? How do I send an Email once I created this PHPMailer object?
  • The IP you're using to send mail is not authorized to 550-5.7.1 send email directly to our servers. I get this error. all I want is a open mail relay.
  • I dont have a static IP. Do you know of any Open mail relay.
  • Additionally see support.google.com/a/answer/176600?hl=en for google SMTP relays.
  • This is the best answer for godaddy php mail() function issues - 2017 - shouldn't have to download PHPMailer or some other 3rd party resource - thanks
  • "READ ON" link is broken
  • Great solution, use it on multiple servers now!
  • Implementing this on my Docker containers for apps that don't use a mailing library.
