Can not send emails
« on: August 21, 2018, 11:23:16 AM »
Hi!
I have this error working with a fresh installation of RoundCube.
<1bccjbh7> SMTP Error: Connection failed: Invalid response code received from server in /home5/xxxxxx/public_html/correo/program/lib/Roundcube/rcube.php on line 1667 (POST /correo/?_task=mail&_unlock=loading1534863215744&_lang=en&_framed=1&_action=send)
[21-Aug-2018 09:05:16 America/Denver] ERROR: Invalid response code received from server (-1)

Do you know what this mean?

thank you

That is a generic error message so to find the cause you have to do some more investigation.

Can other clients connect and send email though the same SMTP server?
Is there any more information on the SMTP server's log?
If you enable smtp_debug in Roundcube does that log contain any more info?
Can you connect via telnet from the webserver to the SMTP server?
