EOP Outbound Connector/"Multiple" smart-host entries. RRS feed

  • Question

  • In EOP "Outbound Connector" when adding "multiple" smart-host entries, I know that the first smart-host to deliver messages to is chosen at random from the list, following that, the connector uses round-robin load balancing to distribute messages among the smart-host entries.

    My question is: what happens if one of the smart-hosts gone off-line for hours, will the EOP deliver emails to it and the senders would receive delivery errors?, or the EOP will sense that it's down and stop delivering emails through it?

  • Hi,

    EOP will try do deliver the emails to the offline smarthost, there is no mechanism that detects offline smarthosts. If one smarthost fails EOP will try the next one. You don't have to worry about senders would receive a non delivery report because EOP will be sent it out much later than EOP tries another smarthost.

    Greetings

  • FOPE allowed multiple MX levels to be configured for smarthosts so we could specify multiple backup paths and only have them used in the event of a failure.

    It seems that EOP has a reduced functionality in this regard?
