Although this post was provoked by my experience trying to fix a health check warning, it isn’t about fixing the config so much as it is about finding the docs that would tell me how to fix the config.

After installing the AWS AMI version and setting up TLS and SMTP, my Passbolt instance is functionally working. But when I run the healthcheck it returns a few warnings, including this:

[WARN] Host availability checking is disabled.
[HELP] Make sure this instance is not publicly available on the internet.
[HELP] Or set the PASSBOLT_EMAIL_VALIDATE_MX environment variable to true.
[HELP] Or set to true in /etc/passbolt/passbolt.php.

This instance is publicly available on the Internet so validating the MX records seems like an essential setting. Following the Help lines, I go find the passbolt.php file. It doesn’t have the setting I need so I track down the defaults file and copy just the one setting over, plus it’s containing array element, into passbolt.php thus:

// Email settings
'email' => [
    // Additional email validation settings
    'validate' => [
        'mx' => filter_var(env('PASSBOLT_EMAIL_VALIDATE_MX', true), FILTER_VALIDATE_BOOLEAN),

I restart nginx but the healthcheck doesn’t report it as changed. When I go looking for the docs that tell me what to restart, I stumble upon a command to restart FPM so I try that. No change. Is there some other process to restart? Can’t find anything that explains these files or what uses them so I punt and reboot the server. Still. No. Change. Arrrrgh!

The HELP lines mention an environment variable so I look for that in the docs and find this page with a notice that reads “These are available for use with both the Docker installation and the Helm installation”. Hmmm…I’m not using either of those. Do these apply to any other installation? Doesn’t say. Well, I don’t have any users yet so I’ll just set it and see what happens. Let me see where and how these are set…wait, what? There’s no mention of that on the page.

As a rule, the docs are authoritative so I always try there first. Failing that I go to the forum to see if anyone else had this issue and fixed it. In this case I did find a few posts where updating the file worked so I know I’m on the right track, but the posts lacked the context to diagnose it when the recommended change has no effect.

Obviously, I’d LOVE to get my MX records validating. But more importantly, I’d love to be able to investigate and diagnose issues myself. So I have to ask…

Where is the doc that explains the settings in the config files, allowable values for each, and what to bounce after making changes? I’ve searched the Developer docs, the Hosting docs, and the Admin docs with no luck. Given the critical nature of these files it seems unlikely such a doc would not exist, so I am assuming the problem here is me dropping the ball on finding it. Any pointers appreciated.

(And in the off chance such a doc does not exist, I’d love some tips on how to get MX validation working. )

Thanks – T.Rob

Hmmm…I thought this was going to be an easy one. Theoretically, warnings surfaced in the health check have docs on how to remediate, right?

Hey @tdotrob welcome to the forum!

This check is actually related to verification of the domain names of email addresses of the users you create in your passbolt instance. So if you have this check set to false you can create obviously fake email addresses, such as me@somefakedomain.local where if you set this to true it will verify the MX record of the domain and not allow you to create accounts with fake domains.

To fix this make sure you are under the passbolt heading and then you pretty much nailed the format:

'passbolt' => [
  'email' => [
    'validate' => [
      'mx' => true

Just be careful that you don’t have this under the Email configuration headingas that is in regards to your SMTP server and this is in regards to a passbolt feature. So, not under this section

    // Email configuration.
    'EmailTransport' => [
        'default' => [
            'host' => 'localhost',
            'port' => 25,
            'username' => 'user',
            'password' => 'secret',
            // Is this a secure connection? true if yes, null if no.
            'tls' => null,
            //'timeout' => 30,
            //'client' => null,
            //'url' => null,
    'Email' => [
        'default' => [
            // Defines the default name and email of the sender of the emails.
            'from' => ['' => 'Passbolt'],
            //'charset' => 'utf-8',
            //'headerCharset' => 'utf-8',

Thanks, that did the trick!
