Contact Centre (CE)

Can someone give me instructions on how to configure a voicemail box to output voicemails to email in CE6, please? I see the Contact Centre unit must be configured in Advanced to send voicemails as an attachment (done) and I see there is a box for me to enter an address (no indication of what the delimiter to be used is, but I only have one address in there for now) and in the IVR I have selected to record voicemail, which works for me, but the emails aren’t being sent out. There are two mailboxes set up already, so presumably it’s not that. Trying to confiure on Pagero.

Do you perhaps know the retention period for the audit trail history?
