exchange 2007 I enabled the our server to accept email from two domains x.com and y.com The primary email address is user@x.com If the user receives an email from sent to user@y.com (not primary), exchange automatically changes the receiver to user@x.com (primary) The problem is I have set up rules in each users outlook such that when ever an email is sent to user@y.com they should go to a separate folder. This allows us to manage and reply back via the correct domain (y.com). Since exchange is doing the changing no emails are ever received in outlook to user@y.com and therefore all emails are mixed together. Does anyone have an idea on what I can do to get exchange to stop with the changes? TIA MH

It sounds like you have the rules setup as "sent to" when it would be best (in this situation) to setup the rule with the "with specific words in the message header" condition. Then you can set it to look for "To: <user@y.com>" DJ Grijalva | MCITP: EMA 2007/2010 | www.persistentcerebro.com

The emails are not even making it to the user inbox addressed to user@y.com Exchange is changing the to address from user@y.com to user@x.com so no matter what rule i have doesnt work or matter Thanks for your reply

External emails the header shouldn't be changed. Internal emails then you are out of luck, as SMTP isn't used. However even depending on the header isn't going to be completely full proof. If the recipient is BCC'd then there is nothing to filter on. The only reliable option is multiple mailboxes. The end user would require permissions on the secondary mailbox to access it and also have Send As permissions. Outlook 2010 makes this combination very easy to work with as you can have multiple accounts and get alerts on all of the accounts.

Sembee thank you for your response. I may have muddy the water by adding the part about the rule and headers. What I am really looking to resolve is why Exchange is changing the "to address" from user@y.com to user@x.com. The emails are sent to user@y.com (same as what is in header) and when processed by exchange, it changes the to address to user@x.com X.com is the default address in exchange for that user Dont know if it matters but this is SBS2008 TIA

Hello, Ideally the simplest and best way to achieve these results is to create two mailboxes so as to not co-mingle the e-mails. Sembee is correct to suggest two mailboxes because when you simplify things, you lower the possibility of errors. For this to work, you will need two AD accounts. One is user1 and the other is user2. The user2 will just be a mailbox enabled dummy accound with full access permissions granted to user1, including send as permission. Give the mailbox an alias: user@y.com and set the send as to user@y.com. Next, create a profile in outlook for user1@x.com and open an additional mailbox in outlook for user@y.com. This way, the two mailboxes will remain separate and you can access either one. When you reply from user@x.com or user@y.com the receiver will see the mail being sent from the account's own alias.

Therefore it will correct the email address to be the default. All others are simply aliases and are for inbound email only. Exchange isn't unusual in this aspect, most other email products work in the same way, even those based on some variant of *nix. However They use SMTP to send email from the client, and you can put anything you like as the from address. Exchange doesn't use SMTP for the client to server communication, so things work in a different way. The headers should still show the correct address and you can filter on them, subject to the limitations with BCC etc that I have already indicated.

Hi muslhead, As I know, Exchange not support to send email as the second SMTP address. So one inbox will unable to meet all your requirements. I think two mailbox is a good solution. It will meet all the requirements. >> What I am really looking to resolve is why Exchange is changing the "to address" from user@y.com to user@x.com. As my test, it is same as what you are encountering. If you set user@y.com as the primary email address, then you will see all the mail send to User@y.com. I think, it is because the legacy DN is unique, Outlook resolve the SMTP address to legacy DN, and display the display name.
