SMTP send: NOT OK(Connection failed: (Code: -1))

[mjcc]

Hi!

I have ticked all the boxes, installing RC v.1.6.9 on a new server #2.

At the last hurdle when testing SMTP, I get this:

SMTP send:  NOT OK(Connection failed: (Code: -1))

I already have RC v1.3.4 running on server #1, which is the same email server, that the above new install is trying to connect to, and connecting to the same email account.

The email config such as TLS, ports, username and passwords are same I use elsewhere with success.


Any ideas?

Here is my config:

$config['db_dsnw'] = 'mysql://roundcube:fzlz%21LygHmPpumH%21TlB6QZPY@localhost/roundCube_1_6_9';
