Missing required header – 400 Bad response

Hi,
I’m getting an error in headers when sending e-mails during user registration.
InvalidParameterValue (client): Missing required header 'From'. - <ErrorResponse xmlns="https://ses.amazonaws.com/doc/2010-12-01/">
When I send test email from plugin settings page, email is sent without problems.

Full error is :
