Email sending issues - using sendmail - /password/email

[Linxord]

Swift_TransportException

Unsupported sendmail command flags []. Must be one of "-bs" or "-t" but can include additional flags.

 

Trying to use sendmail but keep getting error'd out. Even though proper flags are configured in the driver. 

 

'sendmail' => [
                'transport' => 'sendmail',
                'path' => '/usr/sbin/sendmail -bs',
 

----------

Have tried using smtp, but that ends up with another error about:

ErrorException

Undefined index: host

 

host is configured in both config.php and config/mail.php

Did you set the host under smtp?
