Webmail Error Connection timed out110 Can’t open SMTP stream.
ERROR: Message not sent. Server replied: Connection timed out110 Can’t open SMTP stream.
Also when you login the webmail interface works well but when you compsoe the e-mail and click on send the e-mail, the interface stucks..
The possible reason might be that the server firewall ( csf ) might be blocking the SMTP
You’ll need to check the csf configuration file /etc/csf/csf.conf
and check for the parameter “SMTP_BLOCK”
If it is set to
SMTP_BLOCK = “1”
It is enabled thereby it will block outgoing SMTP.
Please turn it to
SMTP_BLOCK = “O”..
And webmail will start responding perfectly..
