SMTP port 25 Blocked
in Help
Hi I am buliding smtp but facing this error : Outbound mail (SMTP port 25) seems to be blocked by your network. You will not be able to send any mail. Many residential networks block port 25 to prevent hijacked machines from being able to send spam. A quick connection test to Google's mail server on port 25 failed.
Please fix it

Hello,
We block several outbound ports for network security. Port 25 is blocked by default. You may request this block be removed by opening a support ticket.
