I would like to test internal mail service with Snow Leopard Server (before trying a service accessible from the web).

I have a dynamic IP from my ISP and I use a DYNDNS to access my server from the web (but maybe it is useless for what I want to do).


1/ The DNS is configured most simply this way :     zone inverse          -               mappage inverse   server.internal.

server.internal.                 zone principale                         -

     server                        machine     

MX mail exchange :          server.internal.                                        5


external DNS requests are sent to (modem/router)


Is it the right way to configure the DNS ? I have no problem to access internal or external addresses.


2/ The Mail service is configured and activated :

Domain name = server.internal.

Host name = server.internal

Activate SMTP, with Kerberos authentication, no SSL

Transit outgoing mail through host : <my ISP SMTP>

Activate IMAP and POP, with Kerberos authentication, no SSL


3/ I have a user 'test' and I activated the mail.

I declared server.internal as mail server, with POP and IMAP access.


4/ I created an IMAP mail account within :

Receiving server = server.internal, port 143, no SSL, Kerberos Version 5 (GSSAPI)

SMTP = server.internal, default ports, no SSL, Kerberos Version 5 (GSSAPI)

For both, username = test and password is the account password


Of course, it does not work : mail cannot connect to the IMAP and to the SMTP server.

But why ?


My network background is light and all I could read about DNS did not help me.


Thanks for your help.

    SAlut Rikki49,


    Je vois que tu viens d'Anger alors je récris en français...


    Je n'ai même pas tenté ton expérience pour la raison suivante:


    J'ai aussi une IP dynamique pour mon serveur Snow leopard et les serveurs smtp qui relaient les mails d'un serveur mail avec une IP dynamique sont simplement blacklistés....


    TU pourras donc éventuellement recevoir des mail via ton serveur et ton dyndns que tu héberges mais tu ne pourras pas en envoyer...


    Dans le meilleur des cas, tu pourras utiliser la réception et l'envoi tant que tu seras dans le même réseau que ton serveur mais une fois que tu seras ailleurs, les problèmes commenceront...


    TOt de bon quand même!
