Hi Everyone,

 

I ran into the following issue and need your ideas of any possible
technical solution.  Please help.......

 

Scenarios:

 

There are two large enterprises A and B in the project consideration. 

 

A has about 100 Windows NT 4.0 domains and 90 Exchange 5.5 organizations
with roughly 100 sites. The current SMTP domain name is sitename.A.gov
so the internet address for each recipient is john.smith@xxxxxxxxxxxxxxx
A has an independent DNS infrastructure supporting its Exchange
implementation. There is no directory or GAL synchronization between
these Exchange servers.

 

B has about 60 Windows NT 4.0 domains and 60 Exchange 5.5 organizations
with roughly 80 sites. The current SMTP domain name is sitename.B.gov so
the internet address for each recipient is john.smith@xxxxxxxxxxxxxxx B
has also its independent DNS infrastructure supporting the Exchange
implementation. There is no directory or GAL synchronization between
these Exchange servers.

 

Both A and B network infrastructure is across continental US
geographically. The two networks have network connectivity through their
Firewalls. The total number of recipients for both A and B is about
500K.

 

Requirement:

 

Both A and B want to share the same SMTP domain name as a secondary
address. In other words, both A and B want to have ABC.gov as a
secondary SMPT domain name and at the same time keep the current
sitename.A.gov and sitename.B.gov as its primary SMTP domain name
address. So, each recipient in A and B will have two valid SMTP address,
one is the primary one and other is the secondary xxx.xxxx@xxxxxxxx

 

Thanks in advance for you help!
