query e- mail address from Groupwise server

Hello,

how can I query our Groupwise Server (Groupwise 2014 SP1 on SLES11 SP3) from our Cisco IronPort email and web security Gateway whether an e-Maill address exist or not. Perhaps over LDAP?
We want to eliminate SPAM-Mails before they reach our Groupwisesystem.

Thanks

  • Hi Hans-Joachim,

    From my experience this is not possible. The reason being that you are unable to query distribution lists and nicknames and thus will reject legitimate e-mail. I stand to be corrected on this, of course, but have personally never gotten my Cisco IronPorts to play nicely with GroupWise in this area.

    Sorry :(

    Cheers,
