This is a common setup for using external MX filtering services. One example is customers on Hosted Exchange who use us for filtering, so our servers are the MX records, then we relay to a subdomain to get the mail to the Hosting Exchange environment... e.g. example.com has MX pointed to us and we relay email sent to u...@example.com to u...@onmicrosoft.example.com.
Another example is where outgoing mail is not allowed on the incoming mail server. In that case, to avoid confusion with multiple accounts, we would typically set up the outgoing server with the same email account addresses, but on the sending server have the accounts relay to the primary incoming server via a subdomain as above. That protects against local mail delivery on the sending server. Setting the sending server up with the same account addresses also give you the ability to switch quickly in the event of an outage at the primary incoming mail server. So, yes, what you are mentioning is common, but at least in our case typically done with the same addresses, not different ones. Hope this helps, Darin.

Why? A recent change by Microsoft Hosted Exchange Servers has disabled the ability to send via the Exchange server. Thus, if a domain was setup on a SmarterMail server that would use that server for sending but have the account reply to the original Exchange server would retain continuity in email processing but still provide the ability to use Outlook and send messages as opposed to using Outlook Web Access which has issues sending attachments, particularly when using Google Chrome. At 5:00 P.M., Friday, January 22, email worked fine. At 5:15 following Microsoft Updates to Hosted Exchange Servers, the Outlook clients were not able to connect. Then attempting to use Outlook Web Access, attachments cannot be sent if using Google Chrome. Rather a mess for the senders. Thus, the reason for the sending email address would relieve situations until an alternate email solution can be established and stop using Microsoft Hosted Exchange altogether.
