SMTP Fail using gmail service

[john28uk]

Hi

I am trying to send email via a webform using smtp.gmail.com, the username and password are correct as on our internal server the mail is sent and recevied, but on our webserver the form shows the error SMTP Error: Could not connect to SMTP host.

Do I need to enable something in the WHM??

Thanks John

Hello,

There is an issues with the firewall. You will have to enable your port in firewall. For the testing you can disable firewall and check your mail.

Hello

Do you have root access to this server? If so, you could install a third-party firewall management utility such as CSF to manage your firewall rules.

Thank you.

Hello, still having issues with this, I have checked my ports and this /http://www.yougetsignal.com/tools/open-ports/ says 465 is open, but I still get the smtp cannot connect error.

Is there anything else I can do to sort this?

Thanks John

Further info, I have run this from root to open up the ports

iptables -A INPUT -m state --state NEW -p tcp --dport 465 -j ACCEPT
iptables -A OUTPUT -m state --state NEW -p tcp --dport 465 -j ACCEPT

Is this the correct way to open the ports?

When I do iptables -L this is the output



No mention of port 465, yet i have opened it

I suggest installing a third-party firewall management utility such as CSF to manage your firewall rules. Also, is this happening for all remote mail servers or is it isolated to Google?

Thank you.

Thank you.

Will CSF be able to manage the firewall already installed on there?? Is this a plugin for WHM?

Not sure, only used the smtp.gmail.com

You can add your existing rules to CSF after installing it, and yes it's a plugin for WHM.

Thank you.
