Topic: Copy of email sent
When using email to send invoices or other documents to clients, no records are kept of such an event. If a client claims that they did not receive the email, one wouldn't be able to say that it was sent to this address at this time.
A solution would be to have all emails sent also sent to a particular email address. This email address could be the email address used in the Company Setup page, but an option for a different email address would be better.
