I am using WordPress 3.5.1. My hoster is 1and1.
I have installed the Newsletter plugin. The test does not work. It shows the following message:
SMTP -> ERROR: Failed to connect to server: Connection refused (111)
The following From address failed: newsletter@trekpyrenees.com
The configuration of Newletter is the following:
– Enable external SMTP: Si
– SMTP host: smtp.1and1.es Port: 25 ‘No secure protocol’
– Authentication. User: newsletter@trekpyrenees.com Password: xxxxx
– Sender email address: newsletter@trekpyrenees.com
My domain is trekpyrenees.com I have sent an email to the hoster. Its answer is
To be able to send emails from a PHP application (like WordPress), in 1and1, you should use the function phpmail/sendmail.
Therefore, my question now is “Does the Newsletter plugin use this function?”
Thanks
Mike
