  • Passbolt Container ( without any volume mounts and an adjusted app.php for allowing self signed certificates.

    ‘url’ => env(‘EMAIL_TRANSPORT_DEFAULT_URL’, null),
    ‘context’ => [
    ‘ssl’ => [
    ‘verify_peer’ => env(‘EMAIL_TRANSPORT_VERIFY_PEER’, true),
    ‘verify_peer_name’ => env(‘EMAIL_TRANSPORT_VERIFY_NAME’, true),
    ‘allow_self_signed’ => env(‘EMAIL_TRANSPORT_ALLOW_SELF_SIGNED’, false),

  • Version 2.12.0

2. Provide a copy of your healthcheck running as the web server user

./bin/cake passbolt healthcheck

3. Describe the problem thoroughly with as much details as possible so that people can reproduce the issues.
– What steps did you take?

  • I already fixed the permission issues in the container for the temp folder, but no luck
  • The cli email check is working (the test email is also received)

– What happened?

  • The email message will not be sent to the users
  • No logs are written by passbolt to /var/www/passbolt/logs

– What did you expect instead?

  • Emails will be sent or an error should be shown

Hi @erdnussflips, I may be misunderstanding but the environment variables you show would be for certs that are NOT self signed. For example, you would want verify to be false.

The URL… Are you attempting to send locally from postfix or something like that or are you going to sign in to a remote server? Credentials are needed for remote servers. For local mail servers the URL can be

Hi @garrett, thanks for your response.
Did you mean the default values in the app.php or my posted environment variables?
My environment variables overwrite the default values from app.php and verify is false (‘0’). If I use “true/false” instead of “0/1” ./bin/cake passbolt send_test_email fails.

EMAIL_TRANSPORT_VERIFY_PEER: “0” // <- this is false
EMAIL_TRANSPORT_VERIFY_PEER_NAME: “0” // <- this is false

I attempting to send through a remote company inhouse SMTP server. I see in my last post, the credentials are empty, but in my config the credentials are present. So that’s not the problem. However the command ./bin/cake passbolt send_test_email is working fine.

EDIT: @garrett I corrected the first post.

You are right…if you use the environment variables, then Passbolt works off of those. The app.php notes you have which say you adjusted them for self-signed certs…those settings are showing the opposite of your environment variables. That was my confusion. Changes there would not be needed…but it’s clear you know that. My fault, sorry.

If I understand correctly, you have the correct IP address of the remote server and credentials to access it, and that remote mail server is configured to receive SMPT on port 25 (and not port 587) and the send_test_email is working fine…but you are saying that ultimately when an end Passbolt user should be getting an email, they are not.

And that makes sense, then, that there would be no logs on the Passbolt server, because it does not appear to be a problem with your Passbolt server. The mail server is either not sending out the messages, or it is but they are going to spam, or its getting blocked by other mail servers, etc. That’s my guess.

(And, final thought, make sure you have the CRON job set to run as well.)

No problem. :slight_smile:

Yes, that’s correct, the server receives SMTP on port 25 and not 587. Yes, send_test_email is working fine but an end Passbolt user is not getting any email.

Good point. I will check this with my colleagues.

I hope, that the CRON job is executed by the official docker image?
But I also fired the cron job manually with su -c "source /etc/environment ; /var/www/passbolt/bin/cake EmailQueue.sender". But no output and users also getting no emails.

Some interesting part is, that su -c "source /etc/environment ; /var/www/passbolt/bin/cake EmailQueue.preview" shows multiple emails. I assume these have not yet been sent?

And the Passbolt server hasn’t internet access, because it’s behind a corporate proxy. I don’t know, whether this is relevant. But the email server (also in the same corporate network) has internet access. :wink:

I would agree with your assumption.

For the URL to the mail server…are you using an IP address or domain? If domain, then the domain and IP may need to be added to the /etc/hosts file. If IP, then I think it’s okay as-is.

Also, there may be a firewall on the mail server that is blocking incoming from the docker IP (since it’s internal use only). Might want to look along those lines too.

Hi @garrett,

it’s working now. I think it has also worked before, because I haven’t changed anything.
But the email delivery was disabled. I enabled it, and now the emails are sent.

Thanks for your help. :slight_smile:

Fantastic! What did you do to “enable email” so it worked?

Under “Administration > Email Notification Settings” all email notifications were disabled. Especially: “Registration & Recovery”.
