e-mail re-routing (same domain)
Hi Everyone,
Bit of a dilemma here...we're an ISP. Our Internet customers share the same email domain name as our internal employees.
Currently all those e-mails use our POSTIX e-mail server. We want to have our employees' e-mail to route through our Exchange server, while keeping our customers on the POSTIX. Again, all e-mail addresses use the exact same @company.com domain name.
Is there any possible way to separate the traffic like that?
Thanks in advance,
Theo

Okay, if I understand correctly, we'll need 1 e-mail server on the outside perimeter, either Exchange, unix or barracuda, which, based on e-mail address, will forward e-mail traffic to either the Exchange server or the POSIX server?
If so, I'm assuming we'll have to set up a separate forwarding rule for every e-mail account? Currently there is really no distinguishing feature between employees e-mail addresses and customer e-mail addresses.
Also, assuming all the above is possible, is it "recommended?" To me, it makes more sense to actually have a create a separate domain name for both.
Thanks,

Once you decide on the flow, you can determine the best method of fowarding.
To help decide, reviewing "Exchange front vs back end servers" and also look into Unix mail server configuration options (easier than Windows in most cases). Having a front end email server as Exchange or Unix sendmail will also provide different options going forward.
