Sending DirectAdmin "new account creation" e-mail through Gmail Apps

Hi,

Is it possible to route DirectAdmin's system messages through Google Apps? That is, I would like DirectAdmin to use Gmail to send out all system e-mails (i.e: account suspension, new account, tickets, etc)?

It might be doable, but only by custom changes to exim.conf to find the system messages, and to use a smarthost router for only those emails.
