Companies are going to like IM2000

Of course, those who are paying attention will have already noticed
one small paragraph in the migration path for companies that 
answers one question that is often asked about MTS softwares:

    "How do I configure my mail system to retain a copy of all
     mail sent to the outside world by my company?"

The answer is, of course, that this is implicit in the very nature of
IM2000, since outgoing mail will sit on the company's message store
and all that has to be done is either (a) ensure that the message 
store software's idea of "deleting" a message is the mere removal of 
it to an archival area, or (b) disable message deletion entirely.  

Another similar oft-asked question is

    "How do I restrict who can send mail to the outside world
     under the aegis of my company whilst still permitting
     employees to send mail internally to one another without 
     restricions?"

The answer, of course, is to run two message stores.  The first has
MSOAP and MSRAP services that are only accessible from within the 
company, and has originator accounts for everyone in the company.  
The second has an MSRAP service that is accessible from Internet, and 
only has originator accounts for those in the company that are 
permitted to send mail under the company aegis to the rest of the
world.  To do so, such people simply switch their originator MUA to use
the originator account for the "external" message store.  Unprivileged
users only have the one originator account, for the "internal"
message store.

One only need run one recipient notification agent, of course, since
it can receive notifications from both message stores (and indeed from 
the rest of Internet), and users thus only need one recipient account
and one recipient mailbox name.  Moreover: One need not also restrict 
people from using outside mail systems from within the company in 
order to make the scheme work, since, unlike in the SMTP-based 
Internet mail case, this isn't a way to bypass the sending restrictions 
in IM2000 Internet mail.
