Hello,
I have three Debian servers with Roundcube.
- On one server Roundcube is working fine when I send message with attachment (1 message of 75 MB sent in 8 seconds).
- On the two others servers I have an error when I send the same message (1 message of 75 MB sent in 74 seconds), but no problem with attachment < 60/70 MB, in logs/errors.log :
<gp1alb94> SMTP Error: Failed to send data. [-1] in /var/www/www.xxxxxx.com/mail/program/lib/Roundcube/rcube.php on line 1702 (POST /mail/?_task=mail&_unlock=loading1584588067868&_framed=1&_lang=fr_FR&_action=send)
<gp1alb94> PHP Error: Invalid response code received from server (POST /mail/?_task=mail&_unlock=loading1584588067868&_framed=1&_lang=fr_FR&_action=send)
Despite the error message, the message is actually sent, but I have the error displayed and afterwards the message is not in the folder "Sent".
Can you help me ?
Thank you very much.
