Topic: domain/mail in external ISP and various Iredmail servers for mailboxes
==== Required information ====
- iRedMail version: 0.8.3
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: Debian 6.0.7 - 2.6.32-5-amd64

I'm trying to implement the following architecture:
Our domain/mailserver is hosted in the ISP. Managed by them. It has 200 mailboxes.
We're downlading the mails in POP3. So, each user downloads its own mails.
We've different locations around the world.
My idea is to have an iredmail server in each site to have a better administration, back-up, user experience/usage, etc.
I've already installed 1 iredmail server with some tests accounts.
I've also enabled fetchmail for those users to get their mails from the ISP and storage in their mailboxes.
They can send mails each other and outside our domain. Example, email@example.com can send/receive e-mails to/from firstname.lastname@example.org (of course, user1 and user2 are created in the iredmail server and also in the ISP)
The problem is when they try to send an e-mail to another user whithin our domain. Example email@example.com sends an e-mail to firstname.lastname@example.org. user1 receives the error message "Recipient address rejected: User unknown in virtual mailbox table". of course, because email@example.com does not exists in the iredmail server but it exists in the ISP.
How this could be configured to work (of course if it's possible) ?
Thanks a lot,
