Hi there,

 

One of my customers is growing and is setting up 4 offices worldwide. Currently the offfices are running and everyone is getting mail from 1 ISP by using POP3 connections. All users do use the same mail domain: USER@COMPANY.COM

 

Now the owner wants SMTP mail for direct delivery of the mail to the head office and the second office. So what will be the best practice:

 

The four offices will be setup as follows:

1: the 'head'-office with 5 users; SBS03 + Exchange; fixed IP.

2: branch office 3 users; SBS03 + Exchange; fixed IP.

3: branch office 1 user; local computer + outlook; dynamic IP.

4: branch office 1 user; local computer + outlook; dynamic IP.

 

In my opinion it can be like:

The ISP changes the MX record so ALL mail goes directly to the head-office. 5 address are taken away here, and all NON-deliverable mail here will be sent to the second office (by sending all undeliverable mail to a host which is the IP address of (the SMPT server of) the second office ...). 3 Addresses are used there.

Now two addresses are left over. What to do with these? How can the two small offices get their mail?

 

I have added an PDF document for the layout and clarification of this.

 

Hope someone does have an idea.

 

I was thinking about making a pop3 connection to the head-office from the local offices. Can that be done? In that case the mainoffice will take away 5+2 addresses before sending through.

 

Thanx,

Jacques.
