All,

I have to create an email address (let's call it
distributionlist@xyz.com) that will, once an email is received,
redirect the content of that message to 10 recipients in 5 different
companies (on 5 domains).

The requirement is that once the recipient receives an email he should
not see who's on the distribution list, therefore all what he should
be able to see is from: distributionlist@xyz.com and To:
distributionlist@xyz.com

The rules (if any) have to be server based.

I've purchased exchange mail and SharePoint hosting for xyz.com
domain, however should I need to purchase different service that's no
problem at all.

The users are on XP, and running, depending on a company, various
versions of Lotus Notes and Outlook 2003

Thanks,

Vasa
