Object only has a single SMTP address, and an x400 address that doest appear to be pointing externally. At this point, it is doing what it needs to do, but not the way I would have performed it. I am just trying to get an understanding of how it is doing this. Based on everything I know, this shouldnt be happening

You can also do contact forwarding using multiple proxy addresses, one email address on the contact is your exchange email then second smtp address could be external address.

Thank you very much for the response. Now I actually know where I "can" set it :) The problem is, that field is blank, so I have no idea how it is getting out of the Organization.

Yes, unless you've specificially configured Exchange to forward unknown recipients to another mail host. You would typically do this when sharing SMTP namespace with foreign mail systems.

 

  1. In Exchange System Manager, expand Administrative Groups, expand Administrative Group Name, expand Servers, expand ServerName, expand Protocols, expand SMTP, and then click the corresponding SMTP virtual server.

  2. Right-click Default SMTP Virtual Server, and then click Properties.

    Note You may have to expand SMTP Virtual Servers before you can click Default SMTP Virtual Server.

  3. Click the Messages tab.

  4. Delete any entries that are displayed in the Forward all mail with unresolved recipients to host box, and then click OK.

Subject: [ExchangeList] Exchange 2003 contact routing handled differently

I am not sure if I missed something long ago, or this is acting weird. If I have a domain catdog.com that my Exchange org is serving, shouldn't all messages sent to <at> catdog.org from internal MAPI clients stay within Exchange? 

 

What is happening (Exchange 2003) ....

 

I have a contact jdaily with smtp address of jdaily-FeBHSwE4lN/QT0dZR+AlfA@public.gmane.org. Of course there is no Exchange mailbox for this address or it wouldn't be a contact. I would figure messages to this address would just be bounced, but instead are forwarded onto a UNIX host which forwards messages to various addresses (like a dist group). 

 

Can anyone explain this? I am at a loss. 

 

 

Thanks, 

 

Doug

room booking site to integrate with exchange 2007

http://www.msexchange.org
-------------------------------------------------------Have a client with a dedicated Exchange
2007 server hosted in a National 
Telco data centre, all staff access exchange via RPC over https.

In each of the 2 offices there are several boardrooms that are used by staff 
and subleasors.  The Subleasors do NOT have any access to the main exchange 
Exchange server.

I am looking for a way to schedule meetings in the boardroom so that the 
free/busy status is accessible to all authorized parties and is accessible 
separately from the Exchange server itself.

Anyone know of a 3rd party service that can intergrate with little to no 
changes on the exchange server.  The SLA's wth the telco preclude installing 
any software they haven't vetted and are explicitly willing to support. I 
only have access to MACD's,. they handle keeping the box running and up to 
date.

SPF and External to External Distribution List

Hello,

 

Perhaps some of you have this scenario in your exchange organization and I would like to know how you accomplish it:

 

·         We have exchange distribution lists with external members (contacts)

·         Other external users write to these list

 

The result is that out domain is sending mails impersonating an external domain. If destination domain use SPF (as we do) will drop down the mails believing we are spammers.

 

How do you solve this situation?

 

Thank you very much for your help.

Re: SPF and External to External Distribution List

I would assume that your DL’s have your own domain name in the SMTP address.  If your DL’s are not assigned your SMTP domain that is listed in your SPF, then of course they will fail.

 

Are you assigning different SMTP Alias’/domain names to your DL’s than what you actually host?


Regards,

Chris

Re: SPF and External to External Distribution List

Yes the list have our own domain name in the SMTP address.

 

We have SMTP address lists like list-32sKj1fRRj1BDgjK7y7TUQ@public.gmane.org (imagine contoso as our exchange domain) . A user of gmail  user1-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org  write to the list and in the list there is a contact member (user2-PkbjNfxxIARBDgjK7y7TUQ@public.gmane.org) . This hotmail user would receive a mail from gmail user but the gmail server detect that it was sent by a CONTOSO mail server. The normal situation is that hotmail drop the message or at least mark CONTOSO as a potential spammer.

 

Up to now we solve this thanks to other mail server (Critical Path) rather than Exchange that changes the envelope FROM address of all the list with a generic address (contoso-owner-list <at> contoso.com). As a result the hotmail user notices that the sender is the gmail user but gmail servers perfectly detects that the mail is sent indeed by CONTOSO servers and don´t drop the mails.

 

We are going to deprecate the old mail server and migrate de lists to exchange. The first tests have not been successful at all. We have no way to tell destination servers that the mail comes from gmail but we are not impersonating but only relying.

Re: SPF and External to External Distribution List

And that’s the problem. SPF is set to only server “x” is allowed to send on behalf of gmail. Since this is a setting in Google’s DNS, you’re not going to be able to get around that.

 

You have to send out as “ <at> contoso.com” with a reply-to  of the original sender (just like you were doing) to insure delivery. You would probably be better served with a listserv service than trying to do this with Exchange.
