Mautic not sending emails: Some .message files in spool have their owner as root

Your software

My Mautic version is: 4.1
My PHP version is: 7.4
My Database type and version is:
mysql Ver 15.1 Distrib 10.3.31-MariaDB

Your problem

My problem is:

I was not receiving emails on my own email account while testing a campaign.
While mautic showed that it has sent the email, I still did not receive it.

So I checked the spool and ran grep to find my email id in the .messages file.
There I noticed that .message file containing my email have its owner as root instead of www-data.

So I manually ran chown -R www-data:www-data /var/spool/ on my mautic root directory.

Then removed my contact from campaign and then re-added to the campaign to trigger the email.

Again searched for email in the spool and sure enough there was a .message file there with its owner as root. WHAT?!

And again, I didn’t receive the email on my account.

what gives?

I schedule my cron jobs in crontab -e as ubuntu which is a non root user.

Is this because I am running my crons as sudo?

Here is my crontab -e of user ubuntu:


*/3 6-23 * * * sudo /home/ubuntu/

*/3 6-23 * * * sudo php /var/www/mautic/bin/console mautic:broadcasts:send

*/3 6-23 * * * sudo php /var/www/mautic/bin/console mautic:emails:send

* * * * * sudo php /var/www/mautic/bin/console mautic:email:fetch

And here is my


sudo php /var/www/mautic/bin/console mautic:segments:update

sleep 30

sudo php /var/www/mautic/bin/console mautic:campaigns:update

sleep 30

sudo php /var/www/mautic/bin/console mautic:campaigns:trigger

I would run the cross as www-data user. This will sort out many of the permission problems
