Trying to send our newsletter this morning Mautic is showing that c. 3000 emails have been sent but they haven’t. There are still 3176 files in /tmp/spool/default (most of which have zero byte count) and when I try and run the following: `/usr/bin/php /var/www/mautic/app/console mautic:emails:send` I get the following error: ```auto [Symfony\Component\Debug\Exception\ContextErrorException] Catchable Fatal Error: Argument 1 passed to Swift_Transport_AbstractSmtpTransport::send() must be an instance of Swift_Mime_Message, boolean given, called in /var/www/mautic/vendor/swiftmailer/swiftmailer/lib/classes/Swift/FileSpool.php on line 169 and defined ``` This is Mautic v2.12.1 and PHP v 5.6.32. I’m not sure what to do next in order to resolve this. Any one had similar or have any idea? ---

I know how to do the first two but how do I update the schema? ---

Thanks but the domain [yourmautic.com](http://yourmautic.com) doesn’t exist. Is that the correct link! ---

I mean to say… Your [mautic.com](http://mautic.com) = your mautic url ---

Hi Sorry for the delay in getting back to you but I have been away and haven’t been able to try this until now. I have resent and all seems to be working. I think that the underlying issue was that the instance Mautic was on had run out of disk space. Thanks for your help.
