Designing new Email Process

[helices]

A company is redesigning their email system, which will look like this:

Incoming
1. Internet mail senders
2. MTA - postfix + various spam processes
3. MDA - Microsoft Exchange 2010
4. MUA - Microsoft Outlook & smartphone apps

Outgoing
A. MUA - same as incoming
B. MDA - same as incoming
C. MTA - same as incoming
D. Internet recipients

Special requirements
a) We have (~100) different domains
b) The From: header field of all outgoing (reply) messages MUST be automatically identical to the incoming recipient (To address

Example:
Incoming To: info@example.com
Delivered to: Group: example.com
Group Members: Alice, Bob, Mary, Tom

Regardless who in Group responds:
Outgoing From: info@example.com
Similarly for other incoming To: help@example_2.net , support@example_3.org , etc.; except, Group members will be different

Request for Microsoft Exchange solution advice
How can we configure Groups in Microsoft Exchange to effectively handle these situations?
We are not currently using Groups & have not found documentation on how to accomplish this

Your group memberships will list the accounts you want the messages delivered to. If you have a list of members for each group then you can easily script the group creation and membership additions.

When a user responds to a message it will come from them, not the group because while the message was addressed to the group, it was forwarded to them as an individual and exists not in the group but in their mailbox.

You can setup a shared mailbox and grant users send as rights to that mailbox to make it look like it is coming from the group.

I hope that helps.

Hi, Mark!

Thank you, for your response.

What do you think about this method?

Incoming mail gets delivered via Distribution Groups

If the To: header remains unchanged at Group member receipt, on Reply use Transport Rules to replace outbound From: header with incoming To: header text

Could this work?

NOTE: I need to flesh out a test scenario to pass on to my Exchange admin, since my expertise is on the MTA side ...

If you can make that work it sounds great.

I hope that helps.
