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

  • Hans-Joachim,

    why don't you just use SMTP? The Ironport will contact the GWIA and one of the first steps is to check if the RCPT is valid. If not, the GWIA will reply with an error and the Ironport can do with the mail whatever it is configured to do. Ours is leaving thconnection to the sending SMTP process open while it checks with the GWIA and will issue an error as well.

    Thanks Uwe,

    we don't use SMTP, because the GWIA is configured to accept all Recipients @mycompany.de. Switches and APC`s can send Mails to our Admins without an own Mailaddress.

    That's the default. Your GWIA will always accept any mail to its own internet domain, regardless the sender. Senders don't need a valid mail address anyway.
    I don't see how this should stop you from letting the ironport do the same.

    It should work. Ironport is exposed to the internet, MX record for your domain probably pointing to the Ironport. Receives a mail from let's say, me. My mail server opens the SMTP connection with the Ironport, and when my server sends the RCPT TO, Ironport will open a connection to the GWIA and forward the commands to the GWIA. If the GWIA replies to the RCPT TO with an OK, the Ironport sends it to my mail server and the communication continues. After the Ironport is finished doing its job, it will continue (or start again) the communication with the GWIA.
