Cannot connect to email host

Posted on February 8, 2018

I am UNABLE to connect to the following services from my droplet:

  1. mail.keith-tan.com:110
  2. mail.keith-tan.com:143
  3. gator4055.hostgator.com:995

However, I am able to connect all three services from an AWS EC2 instance.

Why is Digital Ocean blocking my access? I have no firewall rules in place to block these paths.

Hello, @Geminized

Could you please perform a telnet test from your droplet to all these servers and provide us with the output?

The command syntax is the following:

telnet mail.keith-tan.com 110
telnet mail.keith-tan.com 143
telnet gator4055.hostgator.com 995

You can also make sure that ports 110,143 and 995 are open for outgoing TCP and UDP connections on your droplet.

Let me know if you have any questions.

Regards, Alex
