[Zope] Zope and MS Exchange

[Hans-Peter Knoll]

Hi,

We have a serious problem getting our Zope Mailhost to work. 
Our configuration is as follows:


**************
* INTERNET   *
**************
     / \
      |
      |
      V
********************                       ********************
* Linux-Firewall   *      Port 8080        * Zope-Server      *
* + Gateway        * --------------------> *                  *
* IP:192.168.13.85 *                       * IP:192.168.13.80 *
********************                       ********************
     /\                                          /\
      \                                          /
 Port 25 SMTP                               Port 25 SMTP
        \        **********************        /
         \       * MS Exchange Server *       /
          \----> * IP:192.168.13.100  * <----/
                 *                    *
                 **********************
                  Relay from 192.168.13.80

The Mailhost-Form is filled out as follows:
ID: MailHost
SMTP Host: 192.168.13.100 (or mail.cadwork.de tried alternatively)
SMTP Port: 25

Whenever we try to send mail via Zope we get the error message 'Host not
found'.
Anybody an idea?
Help would be very much appreciated.
Thanx

Hans
