How to Activate E-Mail Functionalities in JDE World in AS/400?

Dear Fellows;

I am not a technical person but only a poor financial accountant :)

We use JDE World setup on AS/400 database (ISeries) . There are some menus
especially in "credit management" where you can send bulk generic messages
to the customers. But it seems that the mechanism is inactive and not
sending any messages through the JDE ERP system... Our concern is ;

to be able to send to our customers and suppliers:

- Monthly A/R and A/P statements;
- Overdue Receivables to the slow motion payors (customers);
- Remittance Advices to the suppliers;
- Dunning Notes to the customers
- Delinquency Notifications to the customers...
- mics....

What type of changes shall be made in the properties of AS/400 Client
Access , Emulator or any IP configuration for e-mail protocols and
lisasons between AS400 database and Microsoft Outlook we use for e-mail
communications?

Thank you very much in advance..
Best Regards,
Ozgur
