Troubleshooting Contact Form | Email delivery fails to strict servers

The CMS Questions
1

Hello Community!

I’ve tried solving this for the past 12 hours, and I’ve decided to ask for help.

I’ve set up an SMTP connection in my config/config.php for Mailjet. I’ve tested it with telnet in my terminal, and my credentials are correct. When sending to a less strict domain like Tutanota, it works fine. However when sending to Gmail or Ionos servers, the message never arrives. I’ve tried adding a SENDER header, I’ve tried using the same FROM and REPLY TO headers. It does not seem to fix the issue.

What would be the best way to troubleshoot this? I don’t think it’s related to SPIF/DKIM/DMARC/MX, because the same SMTP commands worked when used in telnet.

Liebe Grüße aus Wien

Update:

I checked again in Tutanota, where the mail got delivered. The email seems to be sent with Postfix from my server instead of Mailjet SMTP. Have I overlooked something in my config/config.php?

<?php

return [
    'debug' => true,
    'languages' => true,
    'languages.detect' => true,
    'email' => [
        'transport' => [
            'type' => 'stmp',
            'host' => 'in-v3.mailjet.com',
            'port' => '587',
            'security' => 'true',
            'auth' => 'true',
            'username' => 'APIKEY',
            'password' => 'SECRETKEY',
        ]
    ]
];

Bzw. do I need to add something to the controller?

$success = $kirby->email([
                        'template' => 'contact',
                        'from'     => 'me@mydomain.eu',
                        'replyTo'  => $data['email'],
                        'to'       => 'me@mydomain.eu',
                        'subject'  => '[CONTACT FORM] ' . esc($data['name']) . ' sent you a message',
                        'data'     => [
                            'text'   => esc($data['text']),
                            'sender' => esc($data['name']),
                            'email'  => esc($data['email'])
                        ]
                    ])->isSent();

First thing that meets the eye: This must be a boolean not a string.

Hey Sonja,
thank you for your quick reply! Apart from the booleans, I also misspelled SMTP in the config file. What a stupid mistake, seems like I was overthinking the issue haha

Now everything works as intended! Thanks for the help!
