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

问题:

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 = "myemail@gmail.com"; // SMTP username             $mail->Password = "mypasswword"; // SMTP password              $Mail->Priority = 1;              $mail->AddAddress("myemail@gmail.com","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.';             } 

回答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.

回答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

回答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"; 

回答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 ;)

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

回答6:

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.

回答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.

回答8:

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.

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" 

回答10:

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).

回答11:

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

回答12:

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

It also helped me when I commented line $mail->IsSMTP();

Though not sure how.
