Solved Outbound email with Google

[scottharvey]

I am trying to set up outgoing email using Google and I'm getting a Connection timeout error.

Is there any way to determine what the problem is?

Can you verify, that you can reach the smtp.gmail.com server on port 587 just fine on the server? This can be tested on a ssh connection to your server and then attempting telnet smtp.gmail.com 587

Also you might want to take a look at the system logs at journatlct list box, maybe they give more hints.

Here are the logs when I try to connect to the server, I've manually changed my logs to point to example.com

Aug 25 00:04:00 my.example.com node[23958]: Sat, 25 Aug 2018 00:03:59 GMT connect-lastmile Bad Request : Connection timeout
Aug 25 00:04:00 my.example.com node[23958]: Box POST /api/v1/mail/example.com/relay 400 5003.952 ms - 64
Aug 25 00:04:00 my.example.com node[23958]: box:scheduler sync: synchronizing global state with installed app state
Aug 25 00:04:00 my.example.com node[23958]: box:scheduler sync: done

When trying to telnet the command just freezes on the following

root@my:/home# telnet smtp.gmail.com 587
Trying 74.125.24.108...
Trying 74.125.24.109...

If you can ping those IPs (ping 74.125.24.108) successfully, then this is most likely a firewall issue. May it be possible that your VPS provider blocks outbound connections to that port?

@scottharvey Are you on Google Cloud?

@girish I am using Digital Ocean, I found someone suggesting to contact Digital Ocean support in order to open port 587. I sent them an email and I'm just waiting for a reply.

After contacting Digital Ocean support and answering a few questions about my email usage they unblocked port 587 so I can send email now. Thanks for the help.
