webmail error connection timed out 110 Can’t open SMTP stream
If the webmail on cPanel server is giving error as bellow
ERROR: Message not sent. Server replied: Connection timed out 110 Can’t open SMTP stream.
If this error occurs when you try to send e-mails using webmail it is a possibility that the firewall installed on the server is not allowing the connections to the SMTP service
If you have csf firewall on the server please check its configuration for the parameter“SMTP_BLOCK”, the configuration file is “/etc/csf/csf.conf”
If it is configured like below
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..
Well it did at least for me.. hope it does for you as well…
