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

Question

Am trying to send mail to a gmail address but it keeps on getting this error "SMTP -> ERROR: Failed to connect to server: Connection timed out (110)SMTP Connect() failed. Message was not sent.Mailer error: SMTP Connect() failed." What could be the problem?

        require 'class.phpmailer.php'; // path to the PHPMailer class
        require 'class.smtp.php';

            $mail = new PHPMailer();


            $mail->IsSMTP();  // telling the class to use SMTP
            $mail->SMTPDebug = 2;
            $mail->Mailer = "smtp";
            $mail->Host = "ssl://smtp.gmail.com";
            $mail->Port = 587;
            $mail->SMTPAuth = true; // turn on SMTP authentication
            $mail->Username = "[email protected]"; // SMTP username
            $mail->Password = "mypasswword"; // SMTP password 
            $Mail->Priority = 1;

            $mail->AddAddress("[email protected]","Name");
            $mail->SetFrom($visitor_email, $name);
            $mail->AddReplyTo($visitor_email,$name);

            $mail->Subject  = "Message from  Contact form";
            $mail->Body     = $user_message;
            $mail->WordWrap = 50;  

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

Answer 1

Remove or comment out the line-

$mail->IsSMTP();

And it will work for you.

I have checked and experimented many answers from different sites but haven't got any solution except the above solution.

Answer 2

You must to have installed php_openssl.dll, if you use wampserver it's pretty easy, search and apply the extension for PHP.

In the example change this:

    //Set the hostname of the mail server
    $mail->Host = 'smtp.gmail.com';

    //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission 465 ssl
    $mail->Port = 465;

    //Set the encryption system to use - ssl (deprecated) or tls
    $mail->SMTPSecure = 'ssl';

and then you recived an email from gmail talking about to enable the option to Less Safe Access Applications here https://www.google.com/settings/security/lesssecureapps

I recommend you change the password and encrypt it constantly

Answer 3

You've got no SMTPSecure setting to define the type of authentication being used, and you're running the Host setting with the unnecessary 'ssl://' (PS -- ssl is over port 465, if you need to run it over ssl instead, see the accepted answer here. Here's the lines to add/change:

+ $mail->SMTPSecure = 'tls';

- $mail->Host = "ssl://smtp.gmail.com";
+ $mail->Host = "smtp.gmail.com";

Answer 4

Are you running on Localhost? and have you edit the php.ini ?

If not yet, try this:
1. Open xampp->php->php.ini
2. Search for extension=php_openssl.dll
3. The initial will look like this ;extension=php_openssl.dll
4. Remove the ';' and it will look like this extension=php_openssl.dll
5. If you can't find the extension=php_openssl.dll, add this line extension=php_openssl.dll.
6. Then restart your Xampp.

Goodluck ;)

Answer 5

I know its been a while since this question but I had the exact problem and solved it by disabling SMTP_BLOCK on csf.conf (we use CSF for a firewall).

To disable just edit csf.conf and disable SMTP_BLOCK like so:

###############################################################################
# SECTION:SMTP Settings
###############################################################################
# Block outgoing SMTP except for root, exim and mailman (forces scripts/users
# to use the exim/sendmail binary instead of sockets access). This replaces the
# protection as WHM > Tweak Settings > SMTP Tweaks
#
# This option uses the iptables ipt_owner/xt_owner module and must be loaded
# for it to work. It may not be available on some VPS platforms
#
# Note: Run /etc/csf/csftest.pl to check whether this option will function on
# this server
# SMTP_BLOCK = "1" --> this will cause phpmailer Connection timed out (110)
SMTP_BLOCK = "0"

i've had this problem in tell i recive an email from google telling me that someone try to login to your account is it you and i answer yes then it start workin so if this is the case for you look in your email and allow the server

Answer 7

Login your Google account at myaccount.google.com/security go to "Login" and then "Security", scroll to bottom then enable the "Allow less secure apps" option.

Answer 8

Here is a list of this you should look into when dealing with PHPMailer:

1. Enable openSSL by un-commenting extension=php_openssl.dll in your PHP.ini
2. Use $mail->SMTPSecure = 'tls'; and $mail->Port = 587;
3. Enable debugging for if you are going wrong somewhere else like incorrect username and password etc.

Answer 9

You are doing all well. Just you have to check different SMTP ports like 465 and others that works on your system. Another thing to keep in mind to allow access to the less secure apps by google account otherwise it throws the same error.
I have gone through it for a whole day and the only thing I am doing wrong is the port no., I just changed the port no. and it works.

Answer 10

If it works on your localhost but not on your web host:

Some hosting sites block certain outbound SMTP ports. Commenting out the line $mail->IsSMTP(); as noted in the accepted answer may make it work, but it is simply disabling your SMTP configuration, and using the hosting site's email config.

If you are using GoDaddy, there is no way to send mail using a different SMTP. I was using SiteGround, and found that they were allowing SMTP access from ports 25 and 465 only, with an SSL encryption type, so I would look up documentation for your host and go from there.

Answer 11

Mailjet

SMTP SETTINGS

Port: 25 or 587 (some providers block port 25)

I work by changing the port after deploying the app to the server.

• In Debug it worked for me: $mail->Port = 25;
• In Release it worked for me: $mail->Port = 587;

Answer 12

To get it working, I had to go to myaccount.google.com -> "connected apps & sites", and turn "Allow less secure apps" to "ON" (near the bottom of the page).

        <?php
    require 'PHPMailer/PHPMailerAutoload.php';
    
    $mail = new PHPMailer();
    
    $mail->SMTPDebug = 0;                               // Enable verbose debug output
    
    
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->IsSMTP();
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = '[email protected]';                 // SMTP username
    $mail->Password = 'your pass';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to
    $mail->setFrom('[email protected]');
    $mail->addAddress('[email protected]');               // Name is optional
    
    
    $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';
    
    if(!$mail->send()) {
        echo 'Message could not be sent.';
        echo 'Mailer Error: ' . $mail->ErrorInfo;
    } else {
        echo 'Message has been sent';
    }
    
  ?>

THIS WORK FOR ME JUST WHEN YOU WANT TO TEST DON'T USE IDE FOR TESTING THAT BECAUSE PROBABLY NOT WORK IF YOU IN LOCALHOST USE localhost/yourfile.php

Answer 14

the solution is configure the gmail preferences, access to no secure application

Answer 15

Recently Google has lauched something called App Password. By creating an app-password for my mailer instance solved the issue for me.
