  • out of office reply works only on inside domain

    We have a new exchange server standard 2010. We can use out of office automatic reply only on email coming from domain users. External emails can't get oof reply. I'm sure that the message is setup correctly and, in the management console, the option for external oof messages is activated. What can I check?

    Message tracking would be the first thing to check.
    Confirm if the OOTO message is actually going out - I have seen Anti-Spam and AV software block them.

      Ok, I tracked a OOF message and I found this error message from our smarthost: "501 sorry, Mail From must have a valid address. Message rejected. (#5.1.1)"
      What can I do now?

        Interestingly, this appears to break the rules for OOF messages (see http://social.technet.microsoft.com/...rgenerallegacy for example) which apparently should NOT have a sender address.

        Worth talking to whoever manages your smarthost about this one.

          I talked with our smarthost provider and they said that it's normal and that I have to force the "from field" in exchange for the oof reply. What can I do??

            They are the ones that are doing things wrong.

            Specifically they are failing to comply with RFC 2298 - which Exchange does in the way that Exchange creates and processes out of the office. You cannot force Exchange to change its behaviour.

            If they will not change, then time for a new smart host provider.
