Could not instantiate mail function when using craftman Docker-based tool

[Saboteur777]

I got the following error:

Craft\Exception
E-mail error: Could not instantiate mail function

I am using craftman (https://github.com/gabrielmoreira/craftman), my Craft site is now running in a Docker container.

/var/www/craft/app/services/EmailService.php(475)

if ($errorMessage)
466             {
467                 // Fire an 'onSendEmailError' event
468                 $this->onSendEmailError(new Event($this, array(
469                     'user' => $user,
470                     'emailModel' => $emailModel,
471                     'variables' => $variables,
472                     'error' => $errorMessage,
473                 )));
474 
475                 throw new Exception(Craft::t('Email error: {error}', array('error' => $errorMessage)));
476             }

@Saboteur777 This sounds like an issue with your Craft install or with the Craftman plugin; I'm not immediately sure if this is coming from Brief. (Brief relies on Craft's native EmailService to send.)

If you're still seeing this in the future, feel free to reopen this issue with more information, and I'll check it out. Thanks for using Brief!
