Currently when we send emails using the email assist task . The from email address will be showing as the logged in user. If we setup different domains then we will get an opportunity to choose from which domain we want to send emails. We don’t have an option to change the complete “from” email address and replace it with a generic email address.
In future do we have an plans of providing this option to customers so that they can use any other email in “FROM” email address.
