Since we have only an ADSL line on site office if

there any way I could

forward the mails for these staff members

to another Mail Server with

dynamic IP address?

The problem using things like dyndns and forwarding to a dynamic ip is that there is a possibility that when your ip has changed mail would be

attempted to be delivered to the next user that gets your previous ip.

Even with v. low dns timeouts there is still that risk.

Better to get a static ip, or failing that use a pull system like fetchmail.

fetchmail is the way to go on this. It's one of the things it's designed

Btw.: When considering fetchmail, also take a look at getmail.

Your best best is to use qmailrocks installation it works great and includes smtp routes. Use your isp's smtp server to relay everything. I am using it on this server to send you this. There is even a way to set it up with smtpauth

Also I don't have a problem with a dynamic ip since I have a client installed there is a couple of places that seem to do a better job then others. I used dnsexit because it is free so far no complaints.
