Linux lotus notes client configuration

Hi all,I have on my laptop a dual boot (windows XP and Opensuse linux 11.1)

On both systems I have installed a lotus notes client v8.

Both systems use the same notes ID file and the same repositories for the local replicate notes DB.

My society has a domino server and we use it in passthroug on the LAN.

In windows, My notes client works just fine whilst in linux I can receive all mail from outside the society (through the relay) and internal mails, but I’m not able to send something!

Each time I triy to send internal mail or external mail I have the following error:

554 the following mail address xxx@yyy.zzz has been rejected for policy reasons.

can you explain me what I have to modify to solve that issue?

What’s the difference in between linux and windows about that?

In advance, I thank you for you advice.

Cheers,

Charles
