Not allowed to send as from different domain / recipient policy

Hi experts,

As of recently we added a new domain to our exchange configuration using an additional recipient policy. Naturally we contacted our providers to set up the public DNS and required MX records. Internally receiving the mail from @other_company.com is working fine.

The problem occurs when someone is trying to send as the new domain. Say my user account is filtered by both policies and as a result i get the following mail aliasses assigned.

----------Policy one --------------
SMTP : chris.gralike@company.com
smtp : c.gralike@company.com
---------Policy two ---------------
smtp : chris.gralike@other_company.com
------------------------------
Problem:  
Now i try to send from: (using the from header in the new mail) chris.gralike@other_company.com

I receive an NDR stating the following error,
You dont have the right permissions to e-mail to the following addresses. Contact your system engineer (me :/) for more information...
MSEXCH:MSExchangeIS:/DC=local/DC=COMPANY:SERVER30

anyone with any clues?

As far as Exchange/Outlook is concerned, all users only have one email address - the default one. All email the user sends goes out as that address. There is no functionality in Exchange to allow the user to select which address they can send email "as".

You can do so with SMTP/telnet tests because you can put anything you like as the From field. As long as the recipient is valid on the server, Exchange will accept it.

There are various ways to work with this issue
- multiple accounts
- dummy POP3 configurations
- third party tools.

I have outlined the main options here:

Hi,
You need to look at your IMAP service. Check your RDNS settings too

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Hi gupnit,
Does this actually mean that by using the microsoft MAPI (rpc) connection method there is no way for me to send mail from the additionaly added email aliasses?

Because it does look like a Outlook misconfiguration, and not an exchange misconfiguration. i.e.

When using telnet (after removing the sender filters)
the following is returned. (see sniplet)

And is received as expected in the expected mailbox....

Thanks for clearing that up.

This means that this issues has become a functional question instead of a technical one. Reading the suggested solutions using the IMAP4 virtual server just isnt going to work for us, and i think will suggest the multiple accounts sollution with the send as, send on behave permissions set.

Thanks again for the prompt replies :-)

Thanks all, mstha received more points because its a 'cleaner' solution using mulitple accounts (wich was our idea too) just needed to know if it was a technical (conf) problem or functional one. It seems to be the functional one...
