Webmail error Connection timed out110 Can’t open SMTP stream.


If while sending the e-mails using the webmail you are getting error as follows=======================================
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..
