Hi,

I have a contact form on my wordpress website which logs in with a gmail account and it forwards emails from the visitors to the main inbox

The SMTP debugging output is shown below:

2015-11-13 10:53:51 Connection: opening to ssl://smtp.gmail.com:587, timeout=300, options=array (
)
2015-11-13 10:53:51 SMTP ERROR: Failed to connect to server: (0)

Does anyone have a solution since this is a company website which needs to receive emails from customers.

Thank you!

Hi fr2632,



It is definitely an authorisation issue!



2015-11-13 15:23:06 SMTP Error: Could not authenticate.



There have been some changes at Google's side. Perhaps you can try this:



Head over to Account Security Settings (https://www.google.com/settings/security/lesssecureapps) and enable "Access for less secure apps", this allows you to use the google smtp for clients other than the official ones.

Hello fr2632,

This problem is likely related to the Authentication process of Gmail. The SMTP server from Gmail requires authentication with an existing Gmail account. Try changing the port number or the security type.

Change the port to 465 or use TLS instead. More information can be found on the website of Wordpress:

https://wordpress.org/plugins/wp-mail-bank/

** Googlemail - Gmail SMTP Ports & Settings **



  • SMTP Server - Host : smtp.gmail.com - Secure (SSL) - Port 465
  • SMTP Server - Host : smtp.gmail.com - Secure (TLS) - Port 587

Hope this helps for you!

 Thank you Tim for your answer. I have already tried to change ports and SSL or TLS but unfortunately still doesnt work. With the same credential I can access to the gmail account just fine.

The plugin you suggested gives just the same debugging output : 

2015-11-13 14:53:18 Connection: opening to ssl://smtp.gmail.com:587, timeout=300, options=array (
'ssl' =>
array (
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true,
),
)
2015-11-13 14:53:18 SMTP ERROR: Failed to connect to server: (0)
2015-11-13 14:53:18 SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

I am afraid that this is server side issue, some firewall or ports limitation.

Thank you

Hello fr2632,

The error reporting is very minimal. Is it possible to have a more detailed report by using something like 'SMTPDebug = 1'?

Also be sure you're using port 465 when using SSL and port 587 when trying TLS.

Tim, I am sure. The following is a more detailed debugging:

Hello fr2632,

The error reporting is very minimal. Is it possible to have a more detailed report by using something like 'SMTPDebug = 1'?

Also be sure you're using port 465 when using SSL and port 587 when trying TLS.

 

Tim, I am sure. The following is a more detailed debugging:

SMTP Host is smtp.gmail.com.

I apologise for the long post.

Thank you

 

An additinal info : It was working fine before the migration to the KPN server. No settings and such has been modified since then.

Thank you

Hi fr2632,

It is definitely an authorisation issue!

2015-11-13 15:23:06 SMTP Error: Could not authenticate.

There have been some changes at Google's side. Perhaps you can try this:

Head over to Account Security Settings (https://www.google.com/settings/security/lesssecureapps) and enable "Access for less secure apps", this allows you to use the google smtp for clients other than the official ones.

 It works! Thank you! So simple was it!
