  • Sending mail from multiple domains in Exchange 2003

    Hi There !,

    I've been trying to get some answers to a question that was put to me.

    The question is that can multiple domains be hosted on Exchange 2003 ? (Standard / Enterprise). I know that you can receive mails from multiple domains, but can you host multiple domains too ? Lets say if I have 2 domains, abc.com and xyz.com. Could I host both domains on the same exchange server ? I.e. : send and receive mails from both domains?

    If so, then how difficult will it be for one person to switch between the two domains if he needs to send mails from both domains ?

    Any help would be appreciated.

    Thanks !

    1. Yes: you can send/receive emails from both domains:

    2. Each user will have a default domain email address (i.e. acb.com) and a secondary email address with the xyz.com.
    Normally the user will send the emails from abc.com and when he would like to send an email from his second email address (xyz.com email domain), he will type in the "From" field in the outlook, his secondary email domain that he owns.

      Hey Tzahi,

      Thanks for that. However, I can't seem to send out emails from the new domain.

      I get the following bounce back when I try to send a mail using the new address:

      You do not have permission to send to this recipient. For assistance, contact your system administrator.

      Any Ideas ?

      Thanks again !

      Cheers

        Did you add the right recipient policy?
        Did the users got the secondary email addresses?

          Sorry, I have to disagree with Tzahi. Although a user can have any number of secondary email addresses, only the PRIMARY one can be used to SEND email.

          The only way around this is to actually have DIFFERENT mailboxes, one with each email address, and the permissions to SEND AS all of them.

            I edited the default recipient policy, as the article you sent suggested. Every user has the new domain (email) listed in their account. They can receive emails on this domain, but cant send out mails using this new domain.

            Is there something else I need to do ? or am missing ?
