Customise Email Sender
The current options for customising email sender aren't sufficient. You can either configure to send from one address or from the user that is logged in. We have email addresses by functional area so need to configure the Dear emails to be sent by that functional area (e.g. orders@, accounts@, purchasing@ etc.) If we configure to show the sender as the logged-in user then you have multiple people trying to log in with the same user account, which isn't possible.
This could either be configured in the General Settings, so that Purchase Tasks are assigned to one sender and Sales Tasks to another. Or for even better control over Senders these should be configured on the Email Templates, the same way recipients are.
