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

I'm posting because I've already gone through the solutions posted in other questions on here but they haven't helped.

What I am trying to do is send email using Swiftmailer through Google Apps for Business Gmail but I keep getting this error:

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

I know the code is fine because it works on my local machine but not on the production server.

What I have tried so far:

Configuration:

# Swiftmailer Configuration
swiftmailer:
    transport:  smtp
    encryption: ssl
    auth_mode:  login
    host:       smtp.gmail.com
    username:   [email protected]
    password:   applicationspecificpassword
    port:       465

What else can I try? Could this be a DNS issue since I am using Gmails SMTP MX records instead of the servers.

I've just had this issue and after immense search for the solution, it was all a matter of a security setting with my host (In this case Scaleway). I had to open security settings and enable outgoing SMTP.

Open "security groups" settings:

mailer_encryption: ssl
mailer_auth_mode: login
mailer_port: 465

For me the issue was i that I used tls encryption,here are the ports for TLS and SSL. Don`t forget to reboot after changing the env file.

smtp.gmail.com    ---    SSL       ---      465
smtp.gmail.com    ---   StartTLS ---   587

Also,you need to change the security of your google account

The following steps worked for me :

  1. Check if httpd_can_sendmail is on , run this getsebool httpd_can_sendmail

    • When you get: httpd_can_sendmail --> off , run setsebool -P httpd_can_sendmail 1
    • When you get: httpd_can_sendmail --> on that's fine move on step 2.

  2. Check also if httpd_can_network_connect is on, run getsebool httpd_can_network_connect

    • When you get httpd_can_network_connect --> off run setsebool -P httpd_can_network_connect 1
    • When you get: httpd_can_network_connect --> on that's fine move on step 3.
  3. Use the following settings for smtp : 'host' => '64.233.166.108' 'port' => '465'

I'm using Centos

Replacing: smtp.gmail.com with 173.194.65.108 actually worked for me!

I have posted a workaround solution in Swiftmailer Gmail Connection timed out #110 where you can either use IPv4 or IPv6.

If you ever want to return to using Gmail, I've just faced the same problem - the code worked on my local machine but not on a real server - and think I've figured out what is causing it (at least in my case).

It appears that if a server supports IPv6 and IPv4, the server's domain resolves as its IPv6 version so PHP tries to connect to that. But I was finding that smtp.gmail.com did not respond, so after 30 seconds the script just gave up and timed out. You would think that PHP would try IPv4 after IPv6 failed, but no.

So when I swapped in the IPv4 address of smtp.gmail.com (got by ping-ing it), everything worked fine and the email sent. It's not ideal using an IP in place of a domain since it could change, but at least it saves digging up the rest of the server's floorboards :)
