Fetch from two Mailboxes

Fetch from two Mailboxes

We have two mailbox which we receive requests from our customers. Servicedesk@mhemail.org and is-helpdesk@mhemail.org. The second one is monitored manually and used by another region. We'd like to have it fetch from both mailboxes and create business rule " is-helpdesk@mhemail.org
Criteria:To is " is-helpdesk@mhemail.org" Action:Change Request Template to "Mercy Janesville" Can we configure Servicedesk to fetch from both mailboxes? if this is possible can you send us the how to? My assumption is both mailboxes must be on same servername/ip, same username, password and port .
