My org is using multiple Exchange On-premise servers and Exchange Edge servers.
Plus, I am trying to set a 3rd-party Outbound Mail Security System which can be deployed when users send email to external recipients.
1. Original Outbound Mail Flow
(1) User writes mail
(2) Exchange On-prem Server delivers the mail to Edge Server
(3) Edge Server delivers the mail to the external recipient through the internet mail send connector.
2. What I am trying to do
(1) User writes mail
(2) Exchange On-prem Server delivers the mail to Edge Server
(3) Edge Server delivers the mail to a 3rd-party Outbound Mail Security System through the smarthost send connector.
(4) 3rd-party Outbound Mail Security System delivers the mail to the external recipient.
However, there are several issues that I am struggling to address and I need a hand.
Let's say that my org is using 5 domains in the tenant (aaa.com, bbb.com, ccc.com, ddd.com, eee.com.)
Is it possible to make certain mails from aaa.com and bbb.com delivered to the 3rd-party Outbound Mail Security System while other mails from ccc.com, ddd.com and eee.com delivered straight to the recipients?
(Well, I think that it can be possible when I make multiple connectors and rules.
)
This may be like this.
1. Mails (From : aaa.com and bbb.com)
- Mailbox → Exchange Server → Edge Server → (connector) → 3rd-party Outbound System → Recipient
2. Mails (From : ccc.om, ddd.com and eee.com)
- Mailbox → Exchange Server → Edge Server → Recipient
Please give me a hand..
