I am deploying iRedMail for a customer (purchased Easy and Pro this week).  They have some offsite offices that use other email servers.  In the past, they have used MailScanner and MailWatch as their anti-spam server/quarantine portal.  The mail accounts are not held on their mail server, but are scanned and then "passed on" to the other office.  However, they keep the quarantine on their single MailScanner/MailWatch server.  Can iRedMail Pro do this?  For example this scenario:

mail for domain1.com is local iRedMail user accounts
mail for domain2.com is for external company accounts

postfix is setup so that the server accepts mail for both domain1.com and domain2.com.  The mail is scanned for viruses, spam, marked with a [Spam] subject if appropriate, and then either delivered to the domain1.com accounts on the iRedMail server or passed on to the second server.  However, all of the quarantine is held at the domain1.com server.

Does iRedMail Pro have the ability to hold quarantine for mail that is not in the local mail store?

Thanks
