UMA is not physically in front of the mail server. The appliance is connected in the internal network as a server. Since the emails do not pass the appliance, UMA retrieves the emails from the mail server. For this purpose, a hub account must be set up on the exchange server where a copy of every inbound or outbound email is stored. Emails that are sent via the MAPI interface are also copied to this account. In this way, all emails are archived. You can also copy all existing emails to the hub account. If the UMA is then connected to the exchange server, these existing emails are archived (import option).
"If companies are looking for an archiving solution that is totally reliable and audit-proof, then they should look no further than Securepoint Unified Mail Archive (UMA). It is one of the best solutions on the market because it complies with the strictest requirements."TecChannel Thomas Joos
