Cloudron Forum

@girish Wow that worked perfectly, thank you so much!

@robi Thanks for the suggestion! Looks like to setup a DMARC I need a Google organisational account unfortunately and will not work with just a standard account like l have.

Any more suggestions?

Hi everyone,

I'm having some trouble using the outbound relay feature in cloudron.

I'm currently running a Ghost app/site within an Oracle Cloud compute instance.

Oracle block port 25 by default so I have opted for using a relay for outbound mail, using the Google SMTP, which has been setup successfully. This email feature is needed for a Ghost site to invite staff to contribute.

Here is what the email log displays:

And this is what is displayed within the event log:

}

    "<abc123@gmail.com>"
  ],
  "details": {
    "message": "Tried all MXs",
    "delay": 64
  }
}

As you can see, the port (465) is open and it attempts to send the email but the connection closes whilst it is processing and am unsure what can be done to fix this.

Any help is much appreciated!
