Using gmail smtp via Laravel: Connection could not be established with host smtp.gmail.com [Connection timed out #110]

问题

When I try to use GMail SMTP for sending email via Laravel, I encounter the following error:

Swift_TransportException

Connection could not be established with host smtp.gmail.com [Connection timed out #110]

It is the trace of the error:

...
 }
$this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));
if (false === $this->_stream) {
throw new Swift_TransportException(
'Connection could not be established with host ' . $this->_params['host'] .
' [' . $errstr . ' #' . $errno . ']'...

and here are my configuration for mail:

'driver' => 'smtp',

'host' => 'smtp.gmail.com',

'port' => 587,

'from' => array('address' => 'some@example.ir', 'name' => 'some'),

'encryption' => 'tls',

'username' => 'myemail@gmail.com',

'password' => 'mypassword',

'sendmail' => '/usr/sbin/sendmail -bs',

'pretend' => false

I use a shared host and the port 587 on localhost is open.

回答1:

I had the same problem and I resolved it in this way:

'driver' => 'sendmail',

You need to change only that line.

回答2:

After doing lot of research I found this one helpful.

https://www.google.com/settings/security/lesssecureapps.

Open the above link .

Click on Enable. And save it.

Then try to send email again.

For me it worked .

The problem is that smtp.gmail.com is resolving an IPv6 address and that google service only listens on IPv4. What you need to do is set the source IP to ensure domains resolve as IPv4 and not IPv6.

The important method:

    ->setSourceIp('0.0.0.0')

How you might use it in code:

   $this->_transport = Swift_SmtpTransport::newInstance
        (
            'smtp.gmail.com',
            465,
            'ssl'
        )
            ->setUsername('username')
            ->setSourceIp('0.0.0.0')
            ->setPassword('password');

回答4:

Works for me with same settings except encryption and port. Change to:

'encryption' => ssl,
'port' => 465,

Since this is only for localhost encryption line should also be environment specific. So instead above I did following:

env('MAIL_ENCRYPTION','tls'),

Now you can set this in .env file, which is environment specific and should be in .gitignore

I got the same problem using laravel forge + digitalocean.

I find when i try telnet smtp.gmail.com 465

telnet smtp.gmail.com 465
Trying 2404:6800:4003:c00::6d...  # more than 30 sec
Trying 74.125.200.108...          # less 1 sec
Connected to smtp.gmail.com.

Maybe is IPv6 that it Connection timed out.

So,I change gai.conf to prioritize ipv4 over ipv6

vi /etc/gai.conf

#For sites which prefer IPv4 connections change the last line to
precedence ::ffff:0:0/96 100
...
#    For sites which use site-local IPv4 addresses behind NAT there is
#    the problem that even if IPv4 addresses are preferred they do not
#    have the same scope and are therefore not sorted first.  To change
#    this use only these rules:
#
scopev4 ::ffff:169.254.0.0/112  2
scopev4 ::ffff:127.0.0.0/104    2
scopev4 ::ffff:0.0.0.0/96       14

回答6:

Solved mine by changing my .env file as follows:

'driver' => 'sendmail',

回答7:

Try

'encryption' => 'ssl',

'port' => 465,

回答8:

If it is a non-Google Apps account, definitely enable access from less secure apps as suggested. If you don't do that, it won't work.

If it is a Google Apps account (ie it's a business account) then there is an admin panel that governs access. You will need to make sure it is only specifying access by authentication and not by IP, since if it is by IP your IP presumably is not on the list.

The final thing to try is using the IPv4 address of smtp.gmail.com in place of that domain name in your code. I found that mine would not connect using the domain (because that resolved to an IPv6 address) but would connect when I used the raw IP in its place.

回答9:

The error might be due to 2 step verification enabled. In that case you need to create gmail app password and use this as password.

回答10:

I got the same problem using Swiftmailer

Anyway, a quick dirty hack you should not use would be to edit swiftmailer\swiftmailer\lib\classes\Swift\Transport\StreamBuffer.php. In _establishSocketConnection() line 253 replace:

$options = array();

with something like this:

$options = array('ssl' => array('allow_self_signed' => true, 'verify_peer' => false));

This will change the ssl options of stream_context_create() (a few lines below $options):

$this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, 
$errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));

There is a dirty hack for this You can find it here

Also my ENV is set to

MAIL_DRIVER=smtp
MAIL_HOST=mail.mydomain.com
MAIL_PORT=587
MAIL_USERNAME=noreply@mydomain.com
MAIL_PASSWORD=mypassword

回答11:

In your terminal use this command

sudo ufw allow in "Postfix Submission" this enable port 587 for SMTP

回答12:

you need to create 2 factor auth and custom password in google account. Also don't forget to add custom password for every new host you are using.

回答13:

For temporary fix you can resolved the issue by updating env file as 'driver' => 'sendmail'

回答14:

Check your free disk space. On my case, I have 100% used.
