Topic: Forwarding emails to Exchange Server

[Ness]

As a pilot for a longer term project, we are trying to forward emails for three SME user accounts from SME to an Windows Exchange Server, and we also want to use Exchnge as the mail server for these three users, so Exchange will then send to external accounts via SME and onwards.

We don't want to move ALL users to the Windows server, just these three for now at least.

SME sits on the internet router and the Exch box is on SMEs LAN.

We set the "user1" (on SME) account to forward to "user1@the_exchng_server's.domain"

The two machines are on different domains:

examples:

SME is blahblah.co.uk
Exchange Server is on blahblah.com

When we send an email to user1@blahblah.co.uk (for it to be forwarded to user1@blahblah.com, it does deliver the mail but also loops (twice) the email thus:

+++++++++++++++++++++++++++++

Hi. This is the qmail-send program at blahblah.co.uk
I tried to deliver a bounce message to this address, but the bounce bounced!

<user1@blahblah.com>:
This message is looping: it already has my Delivered-To line. (#5.4.6)

--- Below this line is the original bounce.

Why is this happening? Its probably something stupid we did, but we don't know quite what or how stupid!

Can anyone guide us?


Thanks

Ness,
Do you set on EXCHANGE, that all three emails will go to SME?
If so, email user1 will automatically forwarded back to EXCHANGE, as you set it, right?
And this will create LOOP.

Please check.
Cheers,
Wawan

I don't think we set any forwards on Exchange, only for mail coming into SME.

So, mail into SME from the Internet (or locally from other SME users) that is intended for user1 is forwarded to user1 at Exchange for collection by user1's Outlook client.

Conversely, mail from user1 at Exchange should just go out to the intended recpients.

I'll check our set up though and see what I can see.

Thx
