  • forward all mail with unresolved recipents to host

    hello,

    what does this mean?

    does it mean that any messages going in to the exchange and not resolved will be forwarded to that host?
    or does it mean that any messages going out , will be forwarded?


    Thanks.

    It means that any message that cannot be resolved by the Exchange server will be forwarded and handled by this host and will be responsible for generating NDRs if needed.

      Re: forward all mail with unresolved recipents to host

      ok, so its a must.

      well attached the problem that i have.

      a few details: i have a mail relay, which holds the mx records
      and then passes mail to exchange.
      also exchange sends mail to the world through that servers.

      to me at seems that the relay sent the mail to the exchange
      but exchange didnt find the recipient so it sent it back the relay
      but the relay send the mail back to the exchange cause that address belongs to the exchange. and this continues on and on.
      am i correct?
      how do i fix that behaviour?

        in short,
        whenever somes sends mail to an address which i dont have its goes like this

        relay-->exchange--->relay---->exchage --->relay and on on....

        why?

          Unresolved recipients are mail address of hosted domain that don't exist.

          e.g:
          [email protected] exists
          If I send a mail to [email protected], this is an unresolved recipient!

          It has nothing to do with mail to internet. So you must never configure the "forward all mail with unresolved recipents to host " to your mail relay or messages will be looping. This options means an alternative location for messages to non existing mailboxes (default is the POSTMASTER mailbox, with this options they will be redirected to another server)

                Re: forward all mail with unresolved recipents to host

                Hi everyone,

                I'm thinking of a setup like this:
                2 x SBS2003 in 2 different locations serving the same email domain.
                One of them is already installed, working fine.
                I need to be sure that if I set up a "Forward all mail with unresolved recipients to host" to point to my second SBS box it will work.

                Can someone say anything about this ?
                What I found so far is that it can forward to i.e. Unix mail systems...

                Thanks,
